When Walter came down the stairs he saw his team silently standing around waiting for him. "I told you I'm fine. Now will you all please stop looking at me like that? We have a job to do, and that is to track down Collins."

"Homeland hasn't been able to find anything" Sylvester said.

"Then we look harder" Walter snapped. He instantly regretted it, but nothing could be done now. He was longing for some peace and quiet to continue sorting out what had happened in his mind over the past 30 hours. Coming to terms with his limitations wasn't easy, and he still wasn't sure what to do with all the new information. Now that his longing for Paige had been brought to the surface, it was producing an ache in his chest he couldn't understand.

Focus!

"Happy and Toby I want you to look at the data Collins sent us about the things he did to set up the attack. Obviously there are going to be sections of it that he put in there just to throw us off, but we still need to determine his pattern of behavior. Sylvester, look for dark web chatter."

"Okay Walter."

He could feel Paige looking at him from across the room. He needed to make himself appear busy so he logged on to the dark web.

"Walter?" He jumped when he noticed Paige standing in front of him.

"Do you need something?" He found himself unable to make eye contact. It was…painful.

"I'm just worried about you, that's all."

"You don't need to be."

"Maybe you want to talk about it?"

"Talk about what?"

"Your sister. Did you get more bad news? Is that why you…" Walter paused for a moment, then remembered what she said upstairs.

"Oh. Um….I'm busy right now so we can talk about it later."

"Are you sure?"

"Yes."

"I'm here for you Walter" she said putting her hand on his arm.

"Okay." He still refused to make eye contact and she turned around to leave. He inwardly winced, and decided to try and say something. "So um…you and Ralph."

"What?" She asked turning around.

"You went to dinner?" She paused for a moment.

"Oh! Yes we did. On Friday."

"Did you….have fun?"

"We did. Thank you for asking." There was an awkward pause.

"So…um, what did you do?"

"Well, Alex and Ralph came up with a few new ways to communicate with each other which was amazing to watch. And David and I just talked for a while. We talked about the difficulty of finding a school that's suitable for our children, their inability to make friends, being single parents. It was good. I think we'll do it again sometime soon."

It was too much. "Okay thanks for the update."

"Thanks for the update? Walter…"

"We need to focus on getting Collins so, maybe we can talk about this later." He turned away from her, indicating that he was done with the conversation. She lingered for a moment and then slowly walked away.

Walter decided to run some complex equations through his mind to try and temper his emotions and slow his heartbeat. He really did need to focus on finding Collins. Whatever game he was playing, Walter was certain that many more lives were at stake.

"Toby, what's Collins getting at?" He called across the room.

"Revenge. Pure and simple. The nuclear reactor was him trying to prove his worth to the team, and you rejected him a second time. If he did set up that whole thing on Friday just to prove a point to you, he's crazier than even I would of thought. He'll do anything, which makes him extremely dangerous."

"I've already alerted Homeland to the situation, but so far nothing has come up." Cabe said. "We had dozens of people working on it over the weekend, but they weren't you guys. Let's do what we can to get this under control." His phone began to ring so Cabe took it out of his pocket to answer. "Agent Cabe Gallo."

"How did he even get out again?" Happy asked. "Did he just escape or what?"

"Looks like…he was able to swipe a key off of someone and impersonate at janitorial staff. No one noticed." Sylvester said.

Toby shook his head. "That psychiatric ward should be ashamed of themselves. If you've got a patient who's as smart as Collins, a lot more precautions needed to be put into place."

"Alright, Homeland has already been to Collins house and secured it" Cabe said hanging up. "Walter they say that there is something that you should see."

"Just Walter or all of us?" Toby asked.

"Just Walter. They think it has to do with the computer program he had to use on Friday."

"Update me as soon as you have some information" Walter said to the team as he was closing up his laptop. "We shouldn't be long."

As Walter sat in the van headed toward Collins house he was grateful for a few minutes to continue sorting out his mind. He was used to categorizing his thoughts into boxes, which made him so efficient during a crisis. He only ever thought about one thing at a time. This was why he didn't ever want to have strong emotions, because they made everything so complicated. The problem is he thought I'm becoming a better person because of them. Because of her. Walter decided that he would do whatever it took to protect Paige, even if it was from his own awkward, blundering self.

"Can I ask you something?" Cabe said to Walter.

"You will regardless."

"That's true." He paused. "So how are you doing kid? Couldn't help but notice that you seem…distracted."

Walter remained silent.

"Look. I know how important she is to you and I know that you're…hesitant. Believe me, I get it. But Walter, if you keep acting this way you'll lose her entirely. And I know that's not what you want."

"What do you mean, how I've been acting?"

"You haven't looked her in the eye since this morning. And if I've noticed, she's noticed."

"Everything is perfectly fine."

"Just think about what I've said, okay?" Walter looked out the window, and knew that Cabe was right. He would do better next time.

"We're here." Cabe said pulling up the van.

Once they were out of the van and Cabe had verified they were who they said they were Walter proceeded towards Collins house. The first thing he noticed was that all the satellite dishes were gone.

"Cabe did Homeland take Collin's equipment?"

"Negative. Everything is as they found it."

"This is unusual. Collins is used to things being the same, like me. He wouldn't just pack up his stuff and move it."

But once Walter went into the basement he saw that Collins had packed everything up. It was all gone. The papers, the notebooks, the tapes and his timeline of dates. It looked as if no one had been living in the house for years. Walter immediately felt worried. If Collins had decided that his home was no longer important, than his instability was even worse than the team had imagined.

"Walter this is what Homeland wanted you to see." Cabe motioned to a desk with 6 neat papers on it, full of a complex equation. "They couldn't make heads or tails of it."

Walter stared at it for a while, and realized that there were several equations interspersed with one other which when put in the right order made up an equation which could be translated into a message.

"It's another message. Can you get me a pen and paper?" Cabe did so and Walter began re-arranging and solving until he had a complete message.

Round 2 Walter. Are you ready? This one is especially for you. I can't wait to see the look on your face, pal.

"Well, what's it say?" Cabe asked.

Walter handed him the paper.

"That's not good. Is there anything else here that might give us a clue as to what he's doing?"

"I don't think so. Collins removed everything that was here. He knew we would come which is why he left me this message."

"We need to coordinate with the team and see what they've come up with. From the sound of this, we don't have much time."

Once back at the cyclone Walter filled the rest of the team in on what he had seen and the note Collins had left for him.

"Walter this is extremely personal. I know I said that earlier, but we're dealing with a major fixation on Collins part. He wants you to feel something. You rejected him twice so my guess is that he wants you to feel the loss on the same level he did." Toby's eyes widened. "He's going to go for whatever he thinks is most important to you."

"Where's Paige?" Cabe asked suddenly.
