Chapter 1

She's back.

For Olivia, it felt like home. This time, it was really home.

The ride back home was quite bumpy. Her head now hurts. When Walternate put her into the tank, they were just trying to induce her memory. But it happens to be a soft spot and Olivia's now back home. How she actually did it, only she knows. Behind her is the Opera house, which is amber-free. No more zeppelins, no more quarantine zones, no more bossy-yet-friendly Lincoln, no more Alternate-Charlie. The thought of that made Olivia stood still for a while. 'I lost Charlie once again' she thought. But she blinks and she sees the blue sky above her and she feels a little content.

Finally someone walks towards her.

"Agent Broyles! You wouldn't believe what I'm seeing! It's Agent Dunham!"

Oh, it's Walter. Olivia could barely move. Walter walks quickly towards her, seeming anxious. "Are you alright? It was a coincidence. Broyles called Peter and we got here as soon as possible. They thought it was a Fringe case. But it's you! It's you Olivia!"

Olivia can't really smile, although she'd really like to. The brightness of her eyes said everything, and Walter seems to notice that. "It's okay, Olive, it's okay. You don't have to tell me what happened. It's okay. You're going to be okay."

Olive. Olivia's mind went back to the thoughts of when she was just a little kid. Being strapped, injected with needles, being surrounded by weird cables, and this old guy, who's right in front of her right now, was there too, and he told her that it's okay, and she's going to be okay.

Walter gave her a hug, and Olivia can see Broyles approaching. Initially, Broyles didn't really get what was happening. But after seeing the two people in front of him hug, and when he sees the fragile eyes of the agent lying on the side of the scientist right there, he suddenly had an epiphany.

"Agent Dunham. We're.. glad to have you back." he said, and he gave her the typical Broyles smile. Wide, sincere, something she never really saw in Alternate-Broyles.

Olivia managed to smile back and there she was, in front of the Opera house, with probably two of the most important men in her life. She then notices something. Something is missing. Something is not here.

"Peter.. Where's Peter?" she asked, her voice trembling.

Broyles looked at Walter, and Walter's face turned worrisome.

"He's, uh, he's going to be here any minute now, Olivia. He's on his way."

As Walter finished talking, Peter walks through the groups of agents who are currently securing the area. 'That's her.' he thought. He speeds up and walks up the stairs. His face looks dazed, yet concerned.

"Olivia. I.. I.."

Olivia doesn't say a word and she just leans forward and hugs him with all she had. Peter then moves aback and looks at her in the eye.

"Olivia, I'm so sorry."

"It's okay, Peter, I'm back. We're good."

It was awkward. More awkward than when they both met the first time. Suddenly Olivia hears some footsteps coming her way.

And there she is. All blonde, wearing what Olivia's sure comes from her closet, standing right in front of her eyes.

It's the other version of her. The girl whose life she's been living the last couple of weeks. The girl who tricked her. The girl who basically left her on the other side. The girl who stole her life.

Altlivia's face was pale; it was as if she saw a ghost. She couldn't really say a word. She couldn't really believe what she's seeing either. When she woke up this morning, she had no weird feelings, no weird thoughts, and she just thought that today was just going to be like any other day. Broyles called her at around noon to inform her that there was a Fringe case in the Opera house. When she heard him say Opera house, she got chills but she convinced herself it's going to be fine. She then met Peter and she just thought it's going to be the usuals.

"You don't belong here." Olivia managed to say. She looked at Altlivia right in the eye. Altlivia felt slightly intimidated. The look Olivia gave her was more piercing than she thought it would be. 'What would I say to her anyway?', she thought. 'Thank you for letting me live your life and also possibly ruining your universe but fuck, you came back a bit too early? '

Olivia sees all the guilt in Altlivia's eyes. It was her who did the switch, not Olivia. Olivia just remembered that she was with William Bell one time, and suddenly she had a bump on her head and everything was dark. She heard an explosion, and suddenly the next thing she knows is that she's in a cell. Stuck. Alone.

Everyone else didn't know what to say. They stood in silence for a while. Peter finally notices that Olivia is staring at the floor, now shedding a tear. He just grabbed her hand and held it tight. Olivia pulls her hand away and looks at Peter.

"You believed her, didn't you?"

"Olivia.."

"That's why you said you're sorry."

"Olivia, really.."

Altlivia just stood there. If everyone was feeling awkward at that time, she was probably the one who's feeling the most awkward. She couldn't defend herself. She couldn't really say a word. She just witnessed what's happening in front of her, the reunion of two people who are supposedly madly in love with each other. The reunion of a couple which she basically ruined.

"I was over there Peter."

"Olivia." Walter cuts her. "Should we get you into the ambulance?"

"And I had thoughts of you." Olivia just kept talking. She heard what Walter said, but she couldn't really care less at the time. She stares at Peter, blankly. "You were the reason why I was there. I thought I was going mad, but you were the one who kept me sane. You're why I fought to get back home."

"Olivia.."

"But you have her. And you didn't even see the differences, did you?"

"I did, I actually did, but.."

"There are no buts Peter." She then looks at Broyles. "Sir, I think I'm ready to go."

Broyles nodded his head and signaled for the ambulance to come closer.

As Olivia was carried to the ambulance, she couldn't stop looking at Peter. He's standing there, looking at her from time to time, but when she sees Altlivia, and how she looks at Peter, Olivia definitely knows things have changed.

Things have changed a lot when she left.
