Olivia is the first to wake up. She is not surprised to see Peter's eyes closed and hear his shallow breathing when she regains consciousness. His arms wrapped firmly around her bare torso, she obviously isn't going anywhere without waking him. Her hand comes up to brush across his rough stubble, and she leans to place a gentle kiss on his lips.

Without warning, hey are suddenly tangled back together and the kiss has deepened. Olivia laughs against Peter's lips and it sounds like bells to his ears. "Good morning," she giggles. He rests his forehead against hers and rubs the back of her neck.

"Good morning," he replies tiredly. His eyes are still closed, and Olivia watches his face as he lays there, silent. They do not fall back asleep, but simply lay there holding each other.

Minutes could be hours and hours could be minutes, Olivia loses all sense of time as they lay together in bed. The only thing that lets her know to get up is her stomach, which grumbles lightly with hunger.

Peter laughs. "I guess that means it's time for breakfast." He sits up and looks back at Olivia. "Eggs and bacon sound good?"

She nods, smiling. "And toast," she adds. She watches as he leans over to retrieve his boxers. He pulls them on and stands, leaving the bedroom and heading for the kitchen. Olivia lays in bed a few more minutes. Eventually, she stands, holding a sheet around her and pads her way to the bathroom. She checks herself in the mirror. Her hair is slightly disheveled, but otherwise she looks the same as always. She smiles at her reflection.

She leans over to turn on the shower. After checking the water temperature, she drops the sheet and steps underneath the running water. She lets the water cascade over her, relaxing all her muscles and warming her skin. Going through her normal routine, she's out of the shower in under ten minutes.

Stepping out in to the cold air of the bathroom, she quickly grabs a towel off the hook and wraps it around her.

Just as she wipes the condensation off the mirror, Peter calls, "Breakfast." She looks back at her reflection again and something catches her eye this time. There's a red mark where her neck meets her collarbone, where Peter was kissing her the night before. Her fingers graze over the spot tenderly, and she finds herself smiling.

After retrieving some clean clothes, Olivia makes her way to the kitchen. "Mmm," she sighs, the aroma hitting her nose. "Smells amazing." Peter, who has put back on his own clothes, places a plate abundant with food at her place at he table. He hold a fork out towards Olivia and she takes it.

"Dig in," he says as he places his own plate at the table. They both quickly empty their plates and Peter moves them to the sink. He flips on the faucet and rolls up his sleeves.

Olivia moves behind him. "Oh, Peter, you don't have to do that. Just leave them."

He laughs at her. "Let me."

He continues to scrub the plate in his hand as Olivia moves back to the table. She flips open the case file she left there and stares at it, not reading the words in front of her. "You should go talk to Walter," she says suddenly.

Olivia looks up to see Peter's reaction. He says nothing, but sighs heavily and scrubs the dish a little harder.

"Peter."

He sighs again, puts the dish down and turns off the faucet. He leans over the counter, head in his hands. "I know."

Peter's mind can't help but go back to the last time he spoke with Walter.

"Hey, Walter. Have you noticed the way Olivia's been acing lately?"

His father had been working on some project in the lab.

"What was that, Peter?" He looked up from his notes.

"Olivia. Is it just me, or is she acting weird?"

Walter's face turned grave. "I-I don't know." He immediately turned his attention back to his work.

But Peter was suspicious already. "You know, you both have been awfully strange the past week. Did something happen?"

"Of course not, Peter. I'm just working on something..." he trailed off.

"Walter, I know you're lying. If you won't tell me, I'll just go ask Olivia." He stood, as if to leave.

"No!" Walter cried out, surprising Peter. "No, son, don't go."

"Well then, Walter, you're just going to have to tell me what's going on."

"I-I can't. I can't tell you! If I tell you the truth..." he went quiet, as if it was painful to finish the thought.

"Walter, what is going on?" He said each word as if they were different sentences.

Walter fell into his chair. He was obviously distressed. "As a boy, you were very sick."

Peter sighed. "And I almost died. Yeah, you told me. You found some miraculous cure. No matter how you tell it, I still don't remember."

"No, son, you don't understand. You did die," he whispered.

"Walter, I didn't die. I'm right here."

Walter was crying now. "You didn't. He did. My son."

Peter's mind didn't comprehend. "Wait, what do you mean 'your son'?"

Walter's tone got very serious. "I mean, Peter, is that you are not from this world."

There was a long silence, so thick you couldn't cut it with a steak knife.

"I didn't synthesize a cure fast enough. He died. But you, you were still alive! And the other Walter almost found a cure. He did find it, but he didn't know. And then you were going to die again. But I knew! So I made a dose and crossed over." He put his hand over his heart. "It broke. The vial with the medicine to cure you, it was destroyed. I had to make a decision, there wasn't enough time to go back and make more. So I brought you back here, to give you the treatment. I was going to bring you back." His voice got quiet. "I was. But your mother... Your mother saw you and she couldn't lose you, not again. So we kept you, and raised you in he place of the son we lost."

"You kidnapped me!" Peter's voice was loud, angry. "You took me from my life, my home!"

"Son, I-"

"I am not your son."

The lab was quiet except for Walter's sobs.

"What does this have to so with Olivia?"

Walter lifted his head from his hands. "The n-night she c-came to the house. Sh-she knew."

Peter sighed. "I glimmered."

Walter was practically curled up in a ball on the floor. "I'm sorry, I'm sorry..." he repeated between sobs.

Peter had nothing else to say. He left the lab. He called Astrid and asked her to check on Walter in the morning.

Then he headed to Olivia's.

When Peter snapped out of it, Olivia's hand was on his shoulder.

"Peter?"

He looked up at her from his hands. She grabbed his wrist and pulled him towards her, into an embrace.

Peter thought it was strange, Olivia comforting him. Usually it was her who needed comforting, who was holding back tears. Now, it was him.

He inhaled sharply, pulling himself together. "I'll call Astrid, see if he's still at the lab."
