"You think what?" Astrid asked as Peter explained his theory to her.

"I think this girl, Elizabeth, is from another universe. Not our world, not the other side, but a third universe."

"What makes you think this?" Walter asked.

Peter turned to him, "I asked her when the twin towers fell. She said only one of them fell. And that the Pentagon was hit. It doesn't match what happened here or on the Other Side."

"Interesting," He whispered, "Can I meet her?"

"No Walter, "Olivia said, stepping in. Peter hadn't heard her say a word since he'd went in to interview the girl in Jacksonville. "Not until we speak to her again. We're still trying to make her believe that we are her parents."

Peter looked at his watch, "Speaking of which, we should go. We're supposed to see her at the federal building."

Peter and Olivia left the lab and drove to the Boston Federal building. When Olivia got out of the car, Peter stopped her.

"Olivia, are you okay," He asked, touching her arm hesitantly. Olivia just looked down and didn't respond. Peter shifted his weight, "Look Olivia, I know this is a lot to be thrown at us right now. If you want to put us on hold. Or pretend like nothing hap-"

"That's not it," Olivia rushed to say. She took a deep breath.

Peter's eyebrows scrunched in confusion, "Then what is it?"

"Its just a little… disconcerting."

"What is?"

Olivia licked her lips and wrapped her arms tighter around herself, "She looks exactly like me. She looks exactly like I did as a teenager. Almost as if she could be me."

A memory of when Olivia had told him when and how her mom died dawned on him, "Olivia-"

"We should get inside," she said, and that was the end of that. She headed towards the building.

When they went inside, they were told that Olivia was being held in Olivia's office, supervised by an agent.

They stood outside the frosted glass door. Olivia nodded at it and Peter went in. He dismissed the agent and sat down in a chair across from Elizabeth.

"You're still here," she said tonelessly.

"I'm your father," Peter said.

"And that's made such a difference before," She shook her head, "We're in Boston now. Why isn't mom here?"

Peter weighed his answer before giving it, "I told her to stay home," Peter paused then leaned forward in his chair, "Elizabeth-"

"Why are you still calling me that? Until today you haven't called me that since France," She questioned, finally looking at him.

"Elizabeth is what you told them," he countered, nodding at the door, "They've brought you to the FBI. We can't slip up."

"We. Wow been a long time since I heard that one," She turned away from him again.

Peter sat back in his chair, "Elizabeth, I want you to tell me about your family.'

"Why Peter?" Peter had to admit it stung a little bit that if this was his daughter, she called him by his first name.

"Just do it. Tell me what you remember. Tell me about before the way mom told you," Peter threw in the last part hoping it wouldn't mess up his angle, blow his cover.

Elizabeth took a deep breath and began to speak, "This is stupid," she shook her head, "You and mom… You met at a daycare when you were eight. Walter… He owned it or something. He told me once about trying to pair you two up fro some reason. He was always so vague," She laughed, "Well more high than vague.

"Either way, you two became friends. Were inseparable. God hasn't that changed," She scoffed again and closed her eyes.

"Keep going Elizabeth," Peter said a little harsher than necessary. He knew now that whatever universe she was from, Olivia had also been experimented on and he had also been stolen.

"You grew up together. Fell in love.

"But everything changed when she got pregnant with me. You left. You just left us. You knew what Olivia had gone through with her stepfather and you went and did the same to me," She stopped for her second and he could tell she was swallowing back tears. It looked so similar to the way he'd seen Olivia do it a hundred times.

She looked Peter in the eyes, "You know she named me just to spite you. Rini. She knew you'd think it was stupid. Its exactly why she did it.

"Now I'm pretty sure you know the rest, so why don't we just cut the crap."

"Fine," Peter said huskily, "Then I'm going to tell you the truth. I am not your father. And if I were I would never treat you like that."

The girl, Elizabeth or Rini or whatever exactly her real name was, was dumbfounded for a second, "What are you talking about?"

"If your grandfather is anything like my father, and if your mother works where my Olivia does, then this wont sound all that insane to you," Peter paused before going on, "You're from another universe. Not here. I have no idea how, but you crossed here. To another lace that is exactly like your world but a little different. A place where Olivia and I met as children, but were separated. We've just now found each other again and I would never hurt her the way you've relayed to me."

Her eyes suddenly looked solemn, "Am I on the other side?"

"Not your other side. If you were, I wouldn't be here."

"How could you know that?" The girl's voice cracked, and he could tell she was afraid. Whatever this girl had been told by her mother or grandfather of the 'Other Side' terrified her.

Peter took a deep breath, running his hand across mouth, "Its complicated. I cant explain it to you here," He got up and gently placed a hand on Rini's, "I'm gonna get you out of here, hold on tight."

Peter walked out of the room. He saw Olivia, Broyles, Astrid, and a social worker huddled around.

"What's going on?" Peter asked walking up to them.

They all looked up at him but Broyles was the one to speak up, "We can't continue to hold her here," he explained, "There are no official charges."

"Okay that's good," Peter said.

Broyles let out a breath, "Actually I need to speak to you and Olivia for a moment. In my office."

"Okay," Peter said hesitantly and followed Broyles and Olivia.

Once the door was shut, Broyles turned to them and spoke, "We have an interesting situation. She's not even suppose to exist. We can't exactly just send her off with a social worker."

"And?" Peter asked.

Broyles paused, "She claims you are her parents. One of you is going to have to take custody-"

"Your joking," Olivia burst.

"I'm afraid not."

"There's no way."

"Olivia," Peter reproached, a little surprised at her reaction.

"We can't hold her here. One of you is going to have to take her. And that's an order," Broyles announced harshly.

There was a sudden silence in the room, "I'll take her," Peter said, breaking it.

Olivia looked at him without a word.

"Fine," Broyles said, "I'll prepare the paperwork."

Broyles walked out of the office leaving Peter ad Olivia alone.

After a moment, Olivia crossed he arms and took a few steps forward.

"Olivia," Peter began, "One of us had to do it."

Olivia bit her lip, "I just wish this wasn't happening now," She looked at him and her expression made his heart break.

"Olivia, this doesn't have to be an obstacle for us. She's a teenager, she can handle herself," Peter said.

"But she's still there. You're going to have to deal with her. You and I are just putting ourselves back together, and now something else is going to come between us," She spoke quickly.

Peter stepped forward and put his hands on her arms, lowering himself to her eye level, "Olivia, I will not let anything else come between us. Nothing. Understand? Nothing."

Olivia nodded and Peter pulled her into his arms. He knew things were going to be difficult, but he had to help Olivia through it. For their sake.
