I'm really sorry about this large time gap between this chapter and the last. I started school and things have been really busy to me. I'll try to make the waits not so long, but I'm also trying to decide and make some ideas, and plot points for this story as well, so the updates won't be as quick as the past. My sincerest apologies.

Harry POV:

"No, and that's final." Madam Pomfrey said, "You are not allowed to enter. Think of all that could happen," We were standing outside of the doors of the hospital wing trying to see if we could visit Ron, but Madam Pomfrey insisted on no. "We don't even know the reason for this situation, you could get infected,"

"I am kind of 'infected'," I said. At first, I could have laughed so hard when hearing about Draco fainting, however, the situation with this 'virus' was getting worse. I was starting to see why Ron could barely move all day, I wasn't sure that I could have made it to the last class as he did, perhaps I'd just faint in the first lesson of the day like Draco did.

"What?!" Madam Pomfrey gasped. "Why didn't you come earlier? Others could have been exposed as well," Probably not the best idea that I told her that. She quickly grabbed me inside the hospital wing shutting the door behind her. "Don't you think you'll get infected as well?" I asked.

"I'm not sure, but I believe it's worth the risk. Anyway, it seems to only be infecting the students, not a single other faculty member has had any of these symptoms despite spending enough time around the students before they are sent to me," Madam Pomfrey said, leading me to an empty bed and began checking my vitals. "Symptoms?"

"The same as Ron's." I answered, "I only feel really exhausted today,"

"Is there anyone else you know who is infected?" She asked. "You best not keep it a secret."

"No,"

"Mmmhmm," Madam Pomfrey still seemed a bit suspicious of me, but she didn't press any further on the subject. "Okay, I have to check on some of the other students. You are one of the best cases I've seen so far, I trust you to not leave the hospital wing for now."

"When am I going to be let out?"

Madam Pomfrey gave a sigh, her brow furrowing in deep thought. "That depends, we'll have to see."

"How many patients are there so far anyway?"

"That's something you don't to concern yourself with." She walked away.

Annabeth POV:

We were called back to Dumbledore's office that night, our excuse to everyone was that he was going to get our opinion on wanting to stay in Hogwarts during a time like so. "So Madam Pomfrey says this could be a new virus?" I asked after Dumbledore briefed us on the conditions of students.

"Do you believe it may connect to your world?"

"Maybe," Percy admitted. "Last night I had a strange dream. I was somewhere hot and Kelli was there too. We fought a bit, but then I woke up before I could see the result."

"Well, dreams do always mean something," Nico said. "Where do you think you were?"

"I'm not sure. It was just really hot. I didn't see anything overly conspicuous like a landmark of such. What was weird was that she didn't attack the way she normally did."

"What do you mean?"

"Well from all the other times Kelli tried to kill me; she was always full on coming at me with claws and whatnot. This time she was more reserved and keeping her distance instead, making weird movements with her hands instead." Percy tried mimicking her movements, but rather looked like a mime who was doing his first show. "Um, Percy," Nico said. "How about we just use that Pensieve thing Dumbledore has,"

"Good idea," Percy replied. "But will this affect my own memory later on?"

Dumbledore shook his head. "No, it merely allows us to see what you saw. For now, I'll conduct the spell," He brought the tip of his wand to Percy's forehead, murmured the incantation, and removed the tip. A thin substance protruded from Percy's head, going to the Pensieve with Dumbledore's wand in a form that seemed in between liquid and gas. "Are you all going to fit there?" Percy asked. "I know I don't need to see the memory again, but three heads at once is still a lot."

"We'll take turns," I said. "Dumbledore and Nico can go first if they want," They did as such, going right next to each other, they dunked their heads into the Pensieve.

"Do you think if we talked here, they'll hear us?" Percy asked. "Or they can't hear because there seeing my dream and are in another world like situation?"

"Maybe," I replied. "I don't mind if they hear us."

"I don't either. How are things in Ravenclaw?"

"I have a couple of friends, and I think our identities being a secret is well kept from them so far. My grades are good, and I have to say it's interesting being here. How are things going on your end?"

"Well, my grades are good enough. Harry, Ron, and Hermione stopped researching Greek Mythology I think, but every time I feel like they might pick it up again or they'll snoop around and find something out."

"Then we better be extra careful," Soon, Nico and Dumbledore's heads came out from the Pensieve, water dripped down their wet hair as they raised their heads. "She was acting different from what I remember," Nico murmured. He gestured to the bowl. "Annabeth, you next." I nodded my head and plunged into the water.

I found myself looking at Percy from afar. He was wandering around a barren wasteland, one that looked like nowhere we had been before. At one point, he took out his wand and cried out the water charm. His face fell as he watched how at first water emerged from the tip of the wand, but quickly evaporated. He continued to walk for a while, myself following next to his memory. From time to time, he'd call out the summoning charm or check his pockets fro Riptide, but so far nothing else had occurred.

After another few moments of walking, we noticed a figure in the distance, Kelli. She looked the same as I remembered, one mule leg, one metallic. The first thing she did was charge towards him starting the fight, quickly commenting how it was him, and how he deserved to die. What was the most abnormal was how she was firing beams of light or such through her hands rather than battling as she normally did. Expeilliarmus. Petrificus Totalus. I recounted my assumptions on some of the spells she used. At last, Percy had fired his wand using the killing curse. A green beam fired from his wand, but before another light could emerge from Kelli's hands or she would dodge, everything vanished. Percy and her forms completely dissipated as if they disappeared into thin air, the spell vanishing along with them. I pulled my head back up from the Pensieve.
