Whoops so much for a frequent update I'm so sorry! Starting college in a few weeks does that to you haha sighss

anyway, here's the next chapter! :)

["Hope you're ready Dashi, looks like your first stealth mission is coming up a heck of a lot sooner than expected."]

Baymax landed quietly on the roof, above an air vent just big enough for the two brothers to sneak in. Hiro knew it would be too risky and time consuming for them to unarm Baymax and take him in with them, and besides, they needed a quick escape plan.

"So just keep quiet, don't trip over anything, don't let her know we're here."

"Oh really?" Tadashi shot back sarcastically. Hiro may have more experience than him creeping around a super villain's hideouts but he wasn't an idiot. "I thought we were going to barge in the front door and throw her a party."

Scowling at his brother, Hiro slipped through the vent, Tadashi following close behind, and Baymax scanning the warehouse from the roof, radioing in their position relative to Abigail's. Carefully balancing along an overhead platform (Hiro was glad the warehouses were built identical to each other so he had a rough idea of the layout), the brothers reached the area directly above where Abigail was pouring over the blueprints that they had come up with, for the neurotransmitter band and Baymax respectively, machines whirring somewhere just out of sight.

Hiro looked away, unable to wrap his head around the fact that his tech was being used for evil, not again. Why was I so stupid to build those things? Ever the caring older brother, Tadashi squeezed his shoulder reassuringly, slowly guiding him out of the warehouse and back on to Baymax who dutifully took them back to Fred's as fast as possible, his scans of his youngest patient telling him better than to do tricks or stunts.

When the trio touched down on Fred's lawn, the rest were sprawled out on the patio, enjoying the snacks Heathcliff had brought out for them and blissfully ignorant of the danger brewing just a few miles away.

"Welcome back guys! How was the flight?" Fred greeted them enthusiastically, not noticing the brothers' somber attitudes. Hiro brushed past him, sliding down and sitting against the railing as Tadashi filled the team in on the latest developments.

The team visibly reeled back, the thought of having to go through the whole process again numbing them. Honey glanced back at the team's leader, who was now staring blankly at the grain of the wooden flooring. "Oh kiddo, you know it's not your fault right?"

"Yeah." Hiro stood up abruptly, almost knocking over Honey who kneeling beside him. He grabbed Baymax, and climbed back on to the robot.

"Hiro!" Tadashi just managed to grab onto Hiro's arm as the latter was latching on to Baymax again. "What are you doing?"

Hiro's tinted visor hid his emotions as he yanked his arm out of his brother's grasp, commanding the robot to fly, and leaving the rest of the team in the dust.

Tadashi stared after Baymax's smoke trail before slamming his helmet on the ground, "What the hell is that idiot thinking?"

"He turned his and Baymax's radio off," Wasabi informed them nervously a few moments later, scared of what Hiro could do when he was so clearly unstable.

Go Go chewed on her gum, "He's probably headed to the warehouse right? We need to go stop him before he does something he'll regret."

"Yeah, but he kinda took our main mode of transportation with him,"

"Fred?"

Fred looked at them regretfully, "I'm sorry guys, but the 'rents took the chopper yesterday."

"Great," Tadashi threw his arms up in defeat. "Now by the time we get there he'd probably have…" he couldn't bring himself to finish the line of thought.

"I'll go get him," Go Go volunteered. "I am the fastest out of us anyway."

Tadashi nodded gratefully at her. She was the best person to slap some sense into Hiro as well. But Go Go barely had time to snap on her skates when Hiro and Baymax appeared back on the horizon, heading toward the house.

The landing was slightly rougher than usual, and Hiro jumped off his robot before Baymax could even fully touch the ground. Tadashi grabbed him tightly, ripping off his brother's helmet. "What were you thinking?"

"She's gone." Hiro informed them shortly. "I don't know how, or where, but she's gone. It's just perfect."

"Not again."

It didn't register to Hiro exactly who had said it, but it didn't matter. "If we can't beat her to it, we'll beat her at it." He looked up at his team, "And we're going to need a better plan than the last time."

Abigail parked her car in the empty lot of Krei Tech, thankful that everyone left work early. Glancing at the neurotransmitter band in her hand, she felt her determination build up again.

It was time.

She found it almost hilarious how easily she managed to enter the underground lab that held the twin portals; even the toughest security measures in the world give way to those with the appropriate access cards. Abigail hoped the plan, and the neurotransmitter band, would work. But if it doesn't the portals will ruin the building, so it works either way.

As Abigail fired up the portals, she felt her breath hitch as she looked into the abyss than had sucked her in for months, but she willed away those memories and focused at the task at hand. She gingerly slipped on the band, and almost teared up in joy as the microbots slowly began to slip out of the portal, piling up on the floor in front of her. Baymax was harder to retrieve, but after some careful tweaks to the containment field, and she was able to get rid of all the other debris, and saw the white robot floating within sight. She sent a stream of microbots to drag it out, relieved that it was still deactivated.

The scientist wasn't stupid, her father had told her how dangerous Baymax could be, and she wasn't sure exactly what would activate the robot, so she got the microbots to encase it just in case, and carry it back to her car for her, excited to get back to her warehouse and play around with her new toys.

The team headed back to Hiro and Tadashi's garage so they could build whatever they figured out would help them best.

"She couldn't possibly have the blueprints for Baymax's rocket fist and thrusters and stuff, right?" Honey asked.

"But he still has the chip, and that's more than enough."

Tadashi felt his heart break at his brother's tone, he knew the younger boy was blaming himself for everything. "Okay, but the fighting chip is only karate stuff? That means it would have to be in close contact with us to harm us."

"So if our Baymax can rocket fist him down from a distance and then we take out the chip…" Wasabi caught on to his friend's train of thought.

"Baymax fight!" Fred jumped up, before realizing it was slightly inappropriate given the general mood. "But yeah," he coughed, sitting back down awkwardly, "it shouldn't be a problem."

Hiro nodded, ignoring Fred's outburst. "Alright, that's one down. But the microbots…"

"Hiro, you did invent them after all, can't you build a band that could override the control of the original one, or at least shut them down or something?" To be quite honest, Tadashi didn't understand why they hadn't done that before.

"That's genius!"

"Why didn't we think of that before?"

"Well I'm sorry if I was a bit upset the last time around." Hiro snapped uncharacteristically at this team, but went over to his computer and started pulling up the files for his microbots nonetheless.

I'll talk to him, Tadashi mouthed a promise to the rest as they followed Hiro, helping him build the new neurotransmitter the best they could without crossing any lines.

Abigail ordered the microbots to gently set Baymax down in the middle of the warehouse, opening its access port and removing the red chip before inserting her own and closing the port. Baymax activated at that, but without the healthcare chip its start up programming was wordless, and it simply stared at the woman before it.

"Hello Baymax," she smiled. "I'm Abigail, and you only take orders from me, understand?" The robot nodded blankly back at her, understanding but unable to verbally respond. Abigail didn't bother coming up for a new name for the robot, she had much more important things to do. And besides, she thought it would be fun to see the confusion that would ensue if Big Hero 6 decided her to engage her in a battle as they did with her father.

"Good, now what does this do?" She wondered to herself as she nervously replaced the red chip back into Baymax's access port. The robot's eyes turned red and she was scared for a moment, but then it spoke. "Fighting database downloaded." Its voice lacked the kind, caring tone Tadashi had programmed in the healthcare chip, now sounding cold, like any generic speaking computer. "How would you like to proceed?"

Abigail took a few steps back, not sure what 'fighting' entailed. "Show me what you have."

The robot systematically went through the karate moves stored in the chip, with Abigail getting more gleeful with each passing demonstration. "Perfect. Do you think you could use these actions against anyone who tries to oppose me?"

"If you are my commander, I will protect you."

"Good. Now try wearing this."

Later that night, much after the rest of the team had helped to finish up the new neurotransmitter band and left for home, Hiro woke up to Tadashi's computer whirring. The sound was muffled behind the divider between their halves of the room, but Tadashi's light was on as well so Hiro knew for sure his brother was up- Tadashi had to have pitch black darkness to even think of sleeping.

Pushing the covers off, Hiro crossed the room and opened the divider, "Dashi?"

"Hey Hiro," Tadashi turned and smiled at him. The older boy was secretly glad that Hiro had reverted to calling him by his childhood nickname for him after they found him in the hospital. Hiro had announced himself 'too mature for childish nicknames' when he was 11, and it had always been either 'Tadashi' or some version of 'bro' since. "You feeling better?'

Hiro sighed, sitting down on the foot of Tadashi's bed. "I was a jerk to you guys today, I'm so sorry."

"Nobody blames you, kiddo. They all get it, it's crazy to have to go through everything all over again."

"Yeah, but they didn't snap."

"But they're not as personally involved as you are, kiddo. I mean it's not their tech that was stolen or anything."

Hiro nodded, remorse clear in his eyes despite the poor lighting Tadashi's table lamp offered. "I need to apologize to everyone though. I mean like you said, they have to go through everything again as well, they don't deserve to have me taking out my problems on them."

"Yeah, it'll be good if you talk to them in the morning, but trust me, they all understand." Tadashi was so proud of how much his little brother had grown over the past two years. Sure, it had taken unimaginable and heartbreaking tragedy, but the fact that Hiro had taken so much out of it was a true testament to his character.

"Why did I even do it?"

"You're stressed out, Hiro. It's norm-"

"No, as in the microbots. Why did I think it would be a good idea? Why didn't I build something more passive? Why… why couldn't I be more like you, Dashi?"

Tadashi's heart broke all over again for his baby brother, who was doubting his decision of creating one of the best inventions Tadashi had ever seen. "Oh Hiro," he stroked his back as he had done when they were younger, pulling him into a hug. "This was never the plan, and you know it kiddo. Remember when you were first making them? You had all these dreams to use them for transport, construction, all good and helpful things."

"I should have at least made safety catches, or personalized the neurotransmitter, or-" Hiro broke off, burying his head in Tadashi's shirt.

Running a hand through his brother's tangled mess of hair, Tadashi let Hiro cry out all the bottled up emotions he kept to himself, before pulling him up to lay down properly on his bed, knowing that the younger one would not get any sleep on his own tonight. Tadashi quietly finished up what he was working on and turned off the computer and light before settling down to sleep beside his brother.

Nobody knew when Abigail would strike, and if they needed one thing right now, it was enough rest to keep them sane and stable when the situation would eventually call for it.

Thanks for reading! Please review, it really make me feel better about myself and my writing :))

I love you guys!
