Okay, guys, this is the LAST CHAPTER! Just to let you know, once the two Olivias are in the same room together, I start calling Altlivia Altlivia and Olivia Olivia. Hope it doesn't cause confusion! Enjoy!

Walter, Olivia, and Peter set foot in the spot by the lake where they had come from…well, except it was in another universe. Peter would have to take Walter to a secure location where he wouldn't be seen while Olivia went to Fringe Division headquarters where she would put her plan into action. They finally found a cab and jumped in. Olivia handed the cab driver fifty bucks. "You don't tell anyone that you saw us in this cab and there will be more where that came from." The driver happily took the money and drove them to a motel. After Peter checked him and Walter in under a fake name, Olivia left them and went to Fringe Division headquarters.

Olivia was practically shaking with fear on the way to her destination. What are you doing, Liv? You never get scared. Stop being a wimp, she said to herself. Unfortunately, it didn't work. Her plan required a lot more courage than she had ever had to possess.

Olivia luckily got into the building without anyone suspecting anything. Then, finally, she got to her destination—Walter's office. She stood in front of the door, just staring at his name plate for a good minute before finally getting the courage to punch in her access code and open the door. Walter looked startled as she walked in, but quickly regained his usual calm air as he checked the surveillance cameras to make sure that the real Olivia from the Other Side was still in her cell.

"Olivia…completed your mission quickly, I see? That's what I always loved about you, always the fast one. You don't stop at anything."

"Thank you, sir."

"So Peter's back here, working on the machine?"

"Yes, sir. Working on it as we speak."

"Very well. Good job, Agent Dunham. You may return to Peter, now, if you please. I will contact you with more orders tomorrow morning."

"Thank you, sir. But…before I leave, would you mind letting me see your little lab rat? I'd like to see her face once she figures out what's going to happen to her precious Peter." she smirked.

"Why, of course. Don't mind showing her off, it's quite fun."

Olivia smiled back, despite the urge to just punch him in the face right on the spot. But that would come later. Walter motioned for her to follow him down a hall to the other Olivia's cell. Then…she saw her. Her heart almost broke in two. A few months ago, she was trying to kill this woman. Now, staring at her in this tiny little cell, cold and pale, the guilt she felt could fill a stack of buckets as tall as the Eiffel Tower. "Look at her," Walter chuckled. "So helpless…it's quite pathetic, actually." "Yeah…" Olivia said. Now,she said to herself. She quickly turned around pulled out her gun, and shot Walter, right in the head. Then she took out the surrounding security cameras. The other Olivia was now up at the window, looking very confused. Olivia talked into her headset. "Peter, Walter, come RIGHT NOW!" Peter had hacked the headset network so it would be accessible to him and Walter.

Altlivia ran into the cell and grabbed Olivia's arm. "Come on, we gotta get out of here fast." she said urgently.

"No…" Olivia softly said. "I'm NOT going with you, who knows what you're going to do to me."

Altlivia sighed. She did not have time for this. "Look, I know what I did before, but I'm here to help you. Did you not just see me kill my own boss?"

"Where's Peter? Where's Walter?"

"They're coming right now, but we gotta get out of here. By now security's probably after us. They're meeting us outside, now COME ON." she tugged at Olivia's arm. Thankfully, she got up and her and Altlivia ran, side by side, out into the hall. Altlivia ran into the office. Thankfully, security hadn't gotten in here yet. Before, when she came in, she locked it so even the person with the correct passcode could get in. They had to request permission by voice, and obviously, no one was there to let them in. They could bust through the door any minute, though. Altlivia broke into Walter's drawer and took his gun. She handed it to Olivia. Then they both walked over to the door. "You ready?" she asked Olivia. Olivia nervously nodded, and Altlivia opened the door, to find security right outside, staring at her. Then she saw Charlie. He was looking at her, very puzzled. "Liv…what are you doing?" "Charlie, be a buddy right now, please? Just—" "What the hell is going on?" "Charlie I have no time to explain." She started shooting the security guards, but only kicking over Charlie as they sprinted through the building. They ran into more along the way, but thankfully, even Fringe Division security couldn't stand up to two Olivias. They finally got outside.

Olivia was breathless. She saw Peter and Walter, her Peter and Walter, standing right in front of her. It wasn't a dream. This was real. They were really there. "Peter!" she cried. She ran into his arms. Peter held on to her tightly. "Olivia…oh god, Olivia…" he wanted to just stand there and hold on to her forever. But they had no time. They had to get back to the Other Side. Walter hugged Olivia, then asked, "Olivia, we have to get back home. We need your help. Remember what we did last time?" She nodded. Then she turned back to Altlivia. "I…I can't believe I'm saying this, but thank you." Olivia said, smiling. "No problem. I mean, us girls got to help each other out, right? Especially one as good-looking as yourself." she laughed. They shook hands. Then, Peter gave Altlivia a quick hug. "Good luck out here." he said with a smile. She waved goodbye to all of them, and watched them hold hands in a circle, then suddenly disappear.

Suddenly, they were back in Boston. Their Boston, in the middle of the street. Peter looked at Olivia and hugged and kissed her. There were tears of happiness in their eyes. He didn't care if there were people staring, wondering why this man was hugging a woman with wet hair in scrubs in the middle of the busy sidewalk. He had his Olivia, his real Olivia, and he felt like the happiest guy in the world. He pulled away and put his hands on Olivia's face. "Olivia…" "What?" she said. "I love you." She kissed him. "I love you, too, Peter."

THE END!
