The corridor was annoyingly crowded. The drone of voices filled his skull incessantly and it was slowly grating on his already short nerves. It would only be a matter of time before he started finding some… unconventional ways of silencing the noise. Vague impressions of his own times in college drifted at the edge of his consciousness and he turned his attention to the lack of tangible memories as if it would be enough to ease his growing annoyance.

To no surprise, it was rather ineffective and he glanced at the nearest clock for the third time. If his brother was going to take so long, he would have waited elsewhere instead of the herd of a busy corridor.

"Professor!" It wasn't the first time he had heard the call and he ignored it just as he had all the others. Well, tried to. "Professor Gaster!"

His name drew him like a flame did a moth; he found his gaze falling onto a small rabbit monster that came skidding to a stop at his side, a stranger that seemed far too eager to get his attention. But, then, the monster hadn't wanted his attention, now, had it? The monster only became smaller when those tall ears fell back and hung down the length of the monster's back. It pressed a folder to its chest, large eyes belaying its sudden confusion and fear.

The severe expression on his face stayed unchanged, one that many had told him made him look constantly pissed and rather intimidating - if it kept others from badgering him, all the better.

He suppressed the urge to sneer at the rabbit monster. Fear. It was disgusting how quick monsters and humans alike were to fear. Be it change or the unknown, neither group of sentients handled either well.

"Ah, Cesele." His own voice reached out towards himself, yet he had not spoken and he certainly did not know anyone in the corridor. He turned a flat look onto the speaker letting his displeasure show. His brother met his gaze briefly before focusing on the rabbit monster now between them. His brother's hands came up with an encouraging smile, continuing on in Hands and Soulspeak. "What can I do for you?"

The rabbit monster glanced at him again, shrinking away. "I, uh," was stammered out but nothing useful was given. He met the monster's gaze, watching as it cowered even more.

"Is that your project?" his brother asked, gesturing to the folder pinned to the small monster's chest. The small monster nodded. His brother smiled. "Fantastic. And right on time." The small monster didn't hand over the folder until his brother had nearly taken it. "I will get this graded and back to you with everyone else's. Now, if you will excuse me, I have a previous engagement to get to. I will see you in class."

The rabbit monster gave him one last, fearful glance, before taking off down the corridor.

"I believe we had come to an agreement about speaking the shared tongue."

His brother's expression was fond as the other started digging into a pocket. They gained many sidelong glances from those passing. He didn't spare any of them a look. "We had," his brother ceded. "But one moment of a few words is not going to take away our voice."

He could feel the scratching in his own throat. Had there been the normal distance between them, he would have never known his brother was ignoring their agreement until it was too late. They had not healed like last time and they were both hyper aware that they never would.

The lock on the office door gave with a click and his brother entered. He followed after. "You were late."

"I had a few students who needed my attention after class." His brother shrugged. "It had only been a few moments."

His look darkened. "A few moments. Have you forgotten we are on a tight schedule today?"

A sharp rapping came from the doorframe. He turned finding a human in the doorway, hand still raised from knocking. "Dr. Gaster," the human spoke, revealing that this human wasn't another student, let alone a simple civilian. "I am here to take you to Uva upon King Asgore's command. This is an urgent request from His Majesty. It is best for us to leave now."

"Urgent request?" his brother parroted, curiosity coloring the words.

He raised his hands, letting his brother's musings go unanswered. "We shall follow you," he responded, his gestures precise in the air before him.

The human gestured into the busy corridor.

"Wonder why he changed our meeting," his brother spoke once they had stepped outside the building.

The human's brisk pace was leading them to the nearest road access. "Speculating will do us no good. Best wait and find out once we arrive."

"Ah, good. Wing Dings, Wing Decos," King Asgore greeted as they approached the small gathering 20 minutes later. "I am glad to see you both have made it here with no trouble."

"Is something wrong, my King?" his brother inquired with a confused little smile pulling at his expression, hands fluid, almost like an afterthought.

"I am afraid so. Come. The remainder of those I have summoned will not be here for another half hour but this cannot wait."

He shared a glance with his brother as the King turned away. Whatever this was, it was serious.

They followed King Asgore through to the outer edge of Uva. The farther along they went, the greater his suspicion became that their destination was somewhere near the sealed entrance of the Underground.

It wasn't just near the entrance - it was the entrance. The tunnel that led to the seal was barricaded and not a single person going beyond the barricade was without a respirator and full body suit. "There is a leak, then," he surmised.

"It is not that simple," King Asgore corrected.

Both he and his brother turned a disbelieving, concerned look to the King and found a monster there with the weight of the entire Underground resting on his shoulders.

"This is something beyond repairing the seal," he challenged.

King Asgore gestured towards the barricade. "As far as they have discerned so far. I have people working on evacuation plans for Uva. Currently the goal is to discover how large of a problem we have ahead of us before we do anything drastic."

His brother took a step forward. "The toxic atmosphere was potent, Asgore. I doubt a few hundred years changed that. Even if the leak isn't severe and we are able to contain most of it, relocating Uva now may save us having to force everyone to evacuate without their belongings or salvaging what we can. Acting now may save lives."

King Asgore's expression fell. "I remember, Wing Dings. I will look into the evacuation preparations and move it along but I will hold off on calling for a full evacuation until we know for certain."

His brother ceded.

The King showed them where to suit up before leaving. He tracked the boss monster long enough to see the King speak with another personnel. His brother drew his attention away from the interaction by pressing something into his arm.

"Here."

He looked at whatever his brother was offering him and gave the other a flat look when he recognized what it was. "You are aware we do not breathe, correct? Or has your time teaching caused you to forget?"

"The more at ease they are, the easier this will be for us," his brother pointed out. "Besides, it would be better to be safe than sorry. While you may not feign breathing, one careless pull of air could be enough to keep us from ever working again."

Careless. He snatched the respirator from his brother's hand with a glare. He was never careless. Every action was precise and calculated and his brother knew that. Still, his brother did have a point about the ease of playing along. The fewer delays they had to deal with, the better.

The respirator was heavy on his face. When he caught his brother's gaze over those helping them into the full body suits, he gave the other a very flat, very annoyed look that his brother simply smiled at. Just because his brother's argument had been sound didn't mean his patience with the stupidity of it all was going to stretch farther than it normally did.

King Asgore's comment about a leak had dredged up the idea of the clouds the sirens had blared for, a fog of toxin that drifted around but hadn't fully saturated the air yet; instead, they passed through a newly constructed airlock into a tunnel thick with the toxic atmosphere. Visibility dropped to barely ten feet ahead of them if they were lucky. Memories of their earlier years slammed into him, of an Overworld he hadn't thought about in years. His brother staggered steps at his side was tell enough for him to know his brother had been reminded of the same thing.

He wasn't sure if the pulse of magic had been driven by his or his brother's desire to see.

"Stars above," his brother hissed, footfall falling brisk against the floor as they both recentered with the use of magic. They could feel the walls on either side, were certain of where the floor was, and they took the lead much to the apprehension of those that had passed through the airlock with them.

They passed the five minute walk with only their footfall filling the silence between them. The roll of voices drifted at the edge of either of their hearing but the haze and the suits muffled the sounds.

The passageway turned and the sound of voices grew. A check and numerous souls lit up around them. Years of honing their control guaranteed that no one present would have been able to detect it outright; there were a few that grew apprehensive to some degree but none outright reacted.

The toxin was far denser in the space they knew ended a few yards ahead.

"Excellent!" a muffled voice shouted. "More personnel! Please, come closer, come closer. You've still got a good few feet before you run into anything."

"Dr. Talbit, sir, is it such a good idea to meet in the thick of this?" one of the people behind him asked. "Isn't this stuff supposed to be deadly?"

"No supposed to about it, Jack," the muffled voice returned, a person finally coming into view as they finished approaching. The muffled voice belonged to a stout human with salt and pepper facial hair visible in their full face respirator. "We've had three deaths already from this stuff; the most recent one barely had any exposure to it." The stout human turned beady eyes onto him and his brother. "You two must be the Dr. Gaster King Asgore mentioned. He said you two would remember the Overworld and this stuff."

"To a point," he clarified, the Soulspeak naturally going to those within hearing range even if they couldn't see his Hands.

His brother added, "We were alive for the tail end of the Overworld Years, yes, but we were also young and busy working on the UNDERGROUND Initiative. What we remember of the atmosphere itself is probably no more extensive than what you already know."

The stout human nodded. "Long living memory, no matter how faint, is always welcomed. So!" The human clapped their hands together. "Let's get to work, people, and see if we can't get answers for our King and the people!"

It was an hour after the last of the summoned personnel arrived that they found something truly damning. The seal was certainly showing signs of degrading but what holes were in the seal didn't match the volume currently in the tunnel. One of the last to arrive was a geologist - one that even he acknowledged was exceptional in the field - and they were the one to find the crack in the ceiling. To everyone's horror, the fissure went beyond the airlock. It was quickly determined that nothing was coming out of the fissure beyond the airlock towards the whole of the Underground but the fear didn't died.

He and his brother took the geologist and two other scientists along the ceiling of Uva on a set of skull constructs, tracing and marking the fissure until its end halfway down the other side.

"This is bad," the geologist muttered, marking the end point with a large X in the orange paint. "If we don't evacuate now and seal this entire area off, we risk losing the entire Underground."

"Are you sure there's nothing we can do, Lyre?" one of the other scientists asked as his brother drifted over with the other two scientists.

The geologist shook their head. "I wish there was but this is far worse than it looks. All it would take is one good quake and the ceiling would either collapse or separate enough to let more toxic air in. Our best option is to evacuate Uva and seal it off completely. The only saving grace in this is the fact that it's cutting across Uva, rather than towards Snowdin."

"We can't just bury this," the scientist challenged. "Look at where that's gotten us now!"

"Beth," the remaining scientist spoke, their voice soft, coaxing, as they touched the first scientist's arm. "It's ok. It'll be ok." The first scientist shook off the touch but with nowhere to go, the first scientist wrapped their arms around their torso and turned their back to the second. To the second scientist's credit, they didn't look put out by the reaction. "For now, let's return to the others and inform them of what we've found and our suggested course of action. At minimum, Uva has to be evacuated." The second scientist looked to the first. "Maybe we'll get lucky and we'll find a way to keep this part of the Underground open." They turned their gaze back to the rest of the small group. "Until then, though, we will support your findings. If you truly believe this runs a risk for not just this area but the entirety of the Underground, then I'm behind full evacuation and sealing."

The geologist sighed heavily. "I truly hope we find a different solution, too."

The evacuation of Uva went through to the end of the following week. Uva was a mad house of activity but the rest of the Underground stepped up where he doubted it would. Humans and monsters alike came forward to help pack and relocate entire households' belongings into temporary homes across the remaining four zones. The majority were slated to settle in Beuva but a surprisingly large number chose to settle in Snowdin, much to the zone's delight.

Once half of the residents were evacuated, crews started to prep the zone for sealing, which meant the zone getting stripped of anything that could be reused elsewhere. By the time the evacuation had concluded, half of Uva was nothing more than barren cave with turned soil where houses and roads used to be. As time went on, personnel working the stripping project and the sealing project commented how unnerving it was to walk the empty streets among the abandoned buildings, even if they were slated for deconstruction.

"Quite the turnout, huh?" some random human commented as the crowd waited before the remaining tunnel that led to Uva. It had been the main thoroughfare, which made it the largest tunnel out of the four access points. The stage sitting some ways before it wasn't huge but it seemed tiny resting at the foot of the massive archway bookended by the massive stone doors sitting open. There were a few stragglers making their way back through the tunnel towards Snowdin and the waiting crowd.

"That should be the last of them," his brother informed him, joining him in the crowd without fanfare.

"Then that means the ceremony should be starting soon."

His brother nodded. "In theory. Barring any other complications."

"Did you find anyone who was not supposed to be in there?"

"Thankfully no. Two years is apparently long enough for the short living to lose interest in exploring."

Not that there was anything to explore. Beyond barren ground, the only things remaining of Uva were the phantom impressions of roads and homes, as well as whatever paths the personnel had marched out over those two years. "If we are lucky, this will be the only zone we lose."

A hush settled over the surrounding crowd when King Asgore and a number of other important figures stepped up onto the stage. He didn't care to pay any attention to their words. Instead he focused on the double doors as they started to close. There were countless barriers between Uva and Snowdin that had been installed to keep any more leaks of atmosphere from happening. The doors themselves were more symbolic than actually being required - not that several feet thick slabs of stone hurt. What seemed to be the main speech ended just as the doors shuddered closed behind the stage. There was the rolling sound of shifting stone and the glow of heated earth in the door seams before silence chanced across the masses.

As the heated earth cooled, the only indication there had ever been a passageway was the set of carvings that had decorated the door faces. The very air seemed to press down on the crowd as the silence thickened; even the speakers seemed to hesitate.

Just how small would their world get before they made it back to the Overworld?

Smoke. It was the first thing he became aware of as he came to. It was acrid with burning chemicals and burned his sockets, his nasal cavity, even his mouth, as he brought himself back to awareness quickly. There was no sluggishness to his thoughts like he half expected, no temporary lack of memory of what had just happened. He opened his sockets and took in a fuzzy view of the lab from the floor; he wasn't about to waste magic to sharpen his vision when what he saw was clear enough. What half of the lab he could see was disheveled - paper and glass was scattered everywhere - but there was no actual damage to the space.

He knew that wasn't the same for what lay out of sight.

The glass was grit between the palms of his hands and the floor, the sensation of it grinding against bone and floor sending a shudder up his arms and down his spine. It was a nuisance at best and certainly didn't stop him from getting to his feet.

The lack of balance would if he wasn't careful. He grabbed at the table momentarily forgetting what had originally been on it and felt the heat of a flame against the bare bones of his hand and through the sleeve of his lab coat. He looked over as the darkness that had encroached on his vision faded, watching the off colored flames dance happily fueled by the chemicals still burning. His gaze focused beyond the flickering flames to the other half of the lab when he took a step back.

It was completely destroyed.

It looked like someone had set off a bomb on that side of the room. If it wasn't metal or glass, it no longer existed. What metal and glass remained was melted to some degree if not bent or shattered from the force that had caused the mess. There was no evidence to what had caused the explosion. Not even the fire nearest him nor the other two burning on the damaged side of the room gave any information beyond abnormal fuel for the flames closest to him.

Spent magic didn't leave evidence.

His brother was still unconscious at his feet by the time he managed to make it over to where his brother had been thrown. Now moving, bones that ached from the force of the explosion were complaining loudly, stilting his movement to an annoyingly slow pace. It didn't stop him from getting down on one knee and rolling his brother towards him. The amount of effort it took to roll his brother over, though, was mildly concerning.

The lab coat his brother wore was smoke stained and dirty but there were no signs of actual flames touching the fabric, nor any cuts from shrapnel or constructs. He didn't feel any aches in his bones after moving his brother that weren't from his own bruising which ruled out fractures. The fact that his brother was still unconscious, though, was increasing his concern for his twin.

He shook his brother's shoulder. "Dings." He choked on his brother's name, coughing as it agitated what of the smoke had settled in his body. For the third frustrating time in their life his throat burned in a very telling way and speaking their native tongue was not going to help. "Wing Dings," he said again, letting his brother's name be a hoarse croak that hurt. "Wake up, Dings."

Nothing.

All he gained was another coughing fit and an increase in frustration. He staggered back to his feet and nearly fell flat on his face when the world moved more than it was supposed to around him. The counter bit into his ribs as the pinpricks rushing from the base of his spine down his legs banished the strength from his lower extremities. Their magic was too low for him to do anything about it leaving him to wait it out. The fatigue was short lived and he pushed himself back onto his own legs as it started to fade. His strength was far slower to return but his legs stayed underneath him and that was all that mattered.

The tap ran clear when he turned it on; it was cold against his face as he drank from the stream of water. The cold water soothed some of the aching in his throat and in his chest. It should be enough for him to speak louder. He rinsed his face of the remaining lingers of smoke before he turned the tap back off.

There was a muffled sound off to his right. Frowning, he looked over and flinched back from the light that filled his vision. Blinking back spots, he tried to look past the hand he had raised out of reflex but only saw faint shadows in the light.

The muffled sound repeated, though this time it was longer. The light vanished and he lowered his hand. His vision was still light burned when a figure approached him, careful hands wrapping around his shoulders. It took a few seconds of blinking to get the light burns to fade enough to make out the person's face.

King Asgore's face was marred with concern but there was relief at the edges of the boss monster's expression.

"What are you doing here?" he asked, unsure if it was concern or annoyance that he felt towards the King. The burning in his throat was far less than when he had first spoken his brother's name. Before the larger monster could tell him that what he had said was unintelligible, he raised his hands and rephrased in Hands, "Your Majesty, you should not be down here. Let the trained rescuers actually do what they were trained to do."

King Asgore shook his head but whatever the King said, he didn't hear the words. It was like there was a box of glass around his head with walls five inches thick. It muffled the King's voice and any other sounds that had to exist in the room. Had he the magic for it, he would have rolled his eyelights.

"You will have to use Soulspeak, Your Majesty. The explosion has temporarily robbed me of my hearing." In theory. The look of worry that flashed across the King's face, however, informed him quite well that King Asgore had not taken that news all too well. With a hard look, he cut into whatever the King was starting to say. "Your Majesty, I am alive and undamaged. My hearing is not reliant on something that can get irreversibly damaged. It will come back; it will only take some time."

In theory, the King didn't need to know that.

Hours later he found himself wishing his theory hadn't been proven correct. A ringing had settled in his skull after the muffling had subsided but it was too faint to be anything more than a headache. What made it worse was the fact that any noise that was soft, quiet, and of a deeper tone seemed to only amplify the ringing which, in turn, amplified the headache he had pounding at the front of his skull. His only saving grace was the fact that his brother's hospital room was dark and secluded. No one had stopped by in the last two hours and he was relishing the peace for what few moments longer it lasted.

The door latch gave and he looked over at the curtain blocking the door from view. Light spilled across the curtain stretching out before folding back in and extinguishing with the door closing. There had been several shadows so he wasn't overly surprised to see two people step out from behind the curtain a moment later.

"Wing Decos Gaster, I presume." He nodded towards who he was assuming to be the doctor by outfit alone. "I am Dr. Jeremia Halben, one of the doctors who looked your brother over upon arrival. Has he woken up yet?"

He shook his head and ignored the subsequent flare from his headache.

"Well, until he wakes, the only thing that we can inform you is that he appears to be whole and sound. There was a little bit of smoke damage - nothing worse than what you yourself sustained - and that's been cleared out just fine. Once he wakes and we're able to chat with him, we'll be ready to let you both return to your lives. Any questions?" He shook his head again. "Perfect. If you need anything, don't hesitate to ask; Harris here will be your nurse for the next few hours so you can ask for him directly if you need to."

When Harris was replaced by the next crew, they tried getting him to rest. The flat look he had sent each person who tried seemed to work well enough because he never had to resort to Soulspeak. He was too agitated for sleep and the ringing in his skull certainly wouldn't let him sleep even if he had wanted to.

He knew something was wrong well before the doctors did but the specifics came from the doctors.

"The concerns for his mental state had been minimal, solely contingent mostly on his waking," Dr. Halben said six days later. "Over the last three days, it has become apparent that there is some memory loss, but whether or not it's permanent has yet to be determined. Now, the signs of cognitive issues, though. Those are starting to be a bit more prevalent and it will take some time more before we know the full scope of what cognition setbacks he has suffered, along with whether or not he can overcome them."

The ringing in his skull finally made sense.

In the beginning when it never stopped, he had believed there had been something wrong with him despite the doctors assuring him there was not. Now, though, he knew that the ringing wasn't from something he was suffering. Focusing on the ringing only filled his skull with noise but when he half paid attention to it, it almost sounded like jumbled thoughts. Somehow, someway, the cognitive injuries his brother had sustained were showing up in his own skull as a sort of ringing. At least it meant that it would go away once the doctors healed his brother.

They were supposed to heal his brother.

It had been a very long time since he had been overwhelmed by emotions. Usually there was a sort of muted sense to them whenever they swelled within his chest. What boiled out of him and burned out of his control had not been like that.

Six months. Six months wasted at the hospital only for all the specialists in the Underground to tell him that there was nothing they could do for his brother. None of the healing magics worked and there was nothing to influence with chemicals or hormones. All they could offer him was an apology and potential ways to reteach his brother everything he had lost over the months before sending him home with a twin brother whose mental state was worsening by the day. He had been rightfully pissed but it had been manageable; the doctors were just doing what they could within the limitations of their knowledge.

It has been King Asgore's hesitation that had sent him over the edge.

His entire left side still ached from where he had hit the floor after one of the King's attacks had slammed into his right side yet he had been too stubborn in the moment to stay down. Rage, bewilderment, and fear were a potent mix to fight with but King Asgore weathered it all with a level of patience that only infuriated him more. When it was all said and done, King Asgore walked him home to make sure he made it home safe with the magical exhaustion.

The ringing in his head got worse.

There would be times where he could ignore it, and sometimes not even notice it, and then there would be other times when all it did was fill his skull with noise making it impossible to think straight. Work did little to dull the noise but it was better than letting it drive him crazy and when he couldn't think straight because of it, he threw himself even harder into his work, all of his efforts focused on finding some way of helping his brother.

He made his greatest breakthrough that way.

He labeled it Dissociative Acute Amnesia. It wasn't exactly something that could be bottled - not that it stopped him from figuring out how - but he labeled it that anyway. It had fascinating results on those he tested it on and he spent a good number of years remaking people by simply taking away a few memories and replacing them with different ones. A number of monsters and humans died from the first trials but he had expected as much and made sure there were easy ways to cover up the deaths. The challenge came when he started trying it out on those not restricted to his lab.

Filling his brother's shoes was sickeningly easy. The flux of emotions was still uncontrollable but faking them in the presence of those who cared enough to notice discrepancies was child's play. Until he perfected Dissociative Acute Amnesia, he couldn't let his brother beyond the world of their home. Already what little he had given his brother - what little he had changed - had returned some of his brother's ability to think and speak. The ringing was still there but the edges were quieter and what few words his brother could manage had been enough for him to know it was helping the noise in his brother's skull as well. A few more living trials and he would be able to properly repair his brother's mental state.

The entire Underground was in an uproar.

Everything had been going well. He had been doing experiments for years without anyone catching on, manipulating the population around him one person at a time. Just because a few died from it didn't excuse the fervor people sought him out. Forethought made it so that their home was forgotten in the trees of Snowdin. Forethought was the only reason he had any time at all to correct the mistake.

"Decos?"

He didn't look up from his scrawling, magic thick in the air as he multitasked. A vial flew past his brother's head, a hand construct wrapped securely around the glass taking it to where he needed it. "In a moment, Dings. I have to finish this before they arrive."

His brother shifted in the doorway as a tug at their soul made him sigh. He finished the last line of text before facing his brother. The magic kept moving; he did not have time to give his brother his full attention. Not yet, at least.

"Anything I can help with?"

His brother was standing on his own, albeit listing to the left, but the gaze was half focused and the soft smile tired. The unease that had tugged at their soul lingered on the edges of those lightly spoken words. He pulled a smile to his face, suggesting, "If you are able to manage it, I could do with some food."

His brother nodded and shuffled off. If his brother managed to stay on task, it would be one of the better days for his brother. The memory loss had gotten so bad that it was now commonplace for his brother to forget what he was doing mid-task, distracted by a wayward thought or by another task. Dissociative Acute Amnesia was still being perfected and he didn't want to risk his brother's retention of cognitive functions anymore than they were risked. Memories could be added back later.

It also allowed him to work unobserved most of the time.

His attempt at removing them from the collective memory could have been more effective but it was enough. The dispersal of magic and chemicals had been imperfect, leaving some to remember more than others. It certainly gave him plenty to study and work with for when he ever needed to follow through with repeating the dispersal.

Some of those that were long living he personally made sure forgot about him and his brother - the King and a fire elemental that his brother had become friends with being two of a very short list. A good century of staying out of sight would take care of the rest.

Time wore on and he took his time perfecting both Acute and Dissociative Acute Amnesia.

It was a good century and a half before he noticed the aches and pains. The onset had been extremely slow to the point that he hadn't thought to care about it until his brother collapsed in the kitchen and sent excruciating pain through both their forms.

He glared at the test results quelling his frustration with the situation as best he could. He pressed a hand against the massive glass cylinder to keep himself steady as much as it was to reassure himself that everything would work out just fine. He turned a softened gaze to his brother floating inside. Lacking any real skill with healing magic had driven him to resort to other ways of keeping them both healthy. He was very pleased that all the work that had gone into doing so had paid off. The injury sustained in the kitchen was healing well but his brother's body was deteriorating. Whether it was from the Dissociative Acute Amnesia or something else he couldn't tell without doing more research. So far the deaths in the trials had been something other than deterioration like what his brother was suffering.

Had there been any hope of his brother's condition getting better, he would have just done what needed to be done and moved on, but that was not the case. His brother's body would fail long before there were any mental repercussions from the Dissociative Acute Amnesia at this point and he could not afford to be his brother's keeper to the extent needed for someone deteriorating so badly.

He could get his brother some sort of nurse or aid, someone who would keep an eye on his brother for him and who would be a good assistant in the labs when his brother was resting. It would take some work and a good amount of Dissociate Acute Amnesia but it would be worth it.

All he had to do was find a skeleton he could whisk away.

Or make one.
