Chapter one
Morning…

Peter stood in front of the island in the middle of the kitchen; every now and then he'd glance at the door to make sure he was alone. A small smirk broke across his face while putting the finishing touched to his bacon sandwich for breakfast.

"Peter," Olivia's voice calm before she strolled into the kitchen, her hands carefully putting her still damp hair into a ponytail, her suit neat, she glanced over the sandwich on the counter, "I've just gotten off the phone with Astrid, every things a go." Reaching over, she took half the sandwich taking a bite from the corner.

Peter stared from the plate, his attention slowly on to Olivia's hands holding his breakfast, "Would you like some of my sandwich?" He joked before watching her placing it back down.
Olivia raised her eyebrow, pushed the plate lightly towards Peter before letting slip a small smile, "Sorry, in a rush, so much to do." Her voice rushed, the fact she'd spend most of her time here.

It was easier for Olivia to spend time at the Bishop house, even spending a few hours alone in her apartment was enough to make her feel physically sick. Astrid had even offered to help re decorate the place, make it look completely different. But no matter how much the idea would work in logic, in the back of Olivia's mind she'd still she her there, still feel her presence in the walls. Knowing that the other version of her self was there, with Peter, pretending to be her. It was a lot for Olivia to process and whenever it crossed her mind it made everything hurt.

"You know, you're always welcome in the house of crazy," Peter reached over to Olivia, he could always see in her eyes when something was on her mind, he knew the topic, but never spoke of it.

Olivia took in the touch of Peter's hand to her cheek, feeling his fingertips brushing against her skin making it hum with the warmth of his embrace, her eyes closed taking the moment, knowing Peter shifting his weight on the other side of the island. His lips tenderly on her own, Olivia took in the kiss before backing away. "Are you sure this is going to be a good idea?" She whispered as exhaling a soft sigh.

"Yes," Peter replied standing straight again, picking up the piece of sandwich Olivia hadn't taken a bite out of, he lifted it to his lips savouring the flavour, chewing carefully, "I think it's a brilliant idea," He finished chewing and swallowing, his eyes fixed on Olivia.

"Well, do you think he'll like it?" her voice dropped, taking a quick glance behind to the kitchen door, it was still safe to talk. "I mean of everything that's going on, is it wise?"

Peter placed the sandwich piece down, he'd been thinking this over for days, he was trying to make this as normal as possibly, we as normal as they could make it with the events going on around them, "It's a perfect idea," He quickly leant over the counter kissing Olivia's cheek, "You know it's going to be an ideal time for you to. You know…" He gave her his charming smile.

Olivia crinkled her nose, playfully slapping his arm, "Peter Bishop," Her voice a playful mockery, "I hope you're not trying to imply I am going to have to," Olivia bluntly stopped talking hearing the sound of heavy footsteps on the stairs.

"Olivia," Walter's cheerful tone filled the kitchen, "I didn't hear you come in." He finished looking over Peter who'd carried on eating his sandwich.

Olivia turned carefully to see Walter stand in his bathrobe; he must have just woken up, but his eyes still bright. "I didn't leave last night," her voice trying to keep calm, but even after the long time she had known Walter, it felt awkward for her to speak of spending the night with Peter to his face. "Anyway, I have to go, for that thing, because of the," Olivia wasn't sure how to keep cover, but simply reached over the island kissing Peter's cheek, and taking the piece of sandwich she'd already taken a bit out of, "I'll see you tonight." She walked away looking to Walter's confused expression. "I'll see you later Walter," She tapped the doorframe before disappearing.

Walter kept still, he waited until the front door had opened and closed, the sound of Olivia unlocking her car, finally the engine starting and her driving away. "Am I missing something?" Walter asked with his worry lines starting to show.

Peter placed the last tiny piece of his sandwich down, he let out a chuckle, "Don't worry," He smiled, "Just, you know how Olivia can be," He now glimpsed over his watch, "Which reminds me there is something I have to deal with." Picking up the last of his sandwich, "Astrid is going to be picking you up, cos I am taking the car, so be good." He took the car keys from the hook they hung on in the kitchen; he knew it was going to be a long day, but totally worth it.

Walter now stood alone in the kitchen, he exhaled, "Oh," He turned to watch the door open and close, leaving him even more confused. Was there something he was missing? He didn't really know.
All he did know was something was going on, and no one was going to tell him. Then he thought about the days lately, his heart starting to sink, with Peter and Olivia getting close, he was scared. Maybe they were planning to take him back to Saint Claire's, but he shook his head. "No," he spoke out loud, turning to the sound of the car pulling from the drive, "Peter wouldn't." He stopped, thought about it again, this time inhaling trying to push the worried thoughts away.
