So I'm hoping this isn't too mushy after all the angst. Here is the last chapter.
Peter stepped out of the portal and looked around him and the lab that he had stepped into. Walter had dropped a glass container, Astrid looked like she was about to burst into tears and Olivia stood stalk still and looked pale. He could feel Altivia, Alt-Charlie and Lincoln walk out behind him but he didn't care as he took a few more steps into the lab only for Walter to rush at him and cut his arm.
"Ouch, damnit Walter what was that for?" Peter snapped, holding his now bleeding arm which Walter took into his hands and inspected.
"I had to make sure that you were not one of those shape shifters." Walter explained and enveloped Peter in a tight hug. "Oh Peter, I've missed you!"
"You too Walter, I've missed you too." Peter said looking over the older man's shoulder to see Astrid in tears and to see Olivia close to crying herself. He slowly pulled from Walter and made his way over to Olivia, wrapping his arms around her and feeling her body shudder as sobs burst from her lips and tears spilled down her cheeks. "I'm here sweetheart." Peter said holding her tightly to him.
"Are you okay?" Olivia asked pulling back and looking at him carefully.
"I'm fine Livia." Peter said looking at her as well. "You're healthy?"
"You saved me." Olivia said a tear rolling down her cheek. Peter smiled brightly down at her and pulled her into an instantly deep kiss pouring all of his love into her. "How did you get home?" Olivia asked once they pulled apart.
"They brought me to the other lab and let me come home." Peter said gesturing to Alt-Charlie who looked like he had seen a ghost since he was so pale, Lincoln who was looking around the lab in interest and Altivia who was getting glares from Walter and Astrid making her look rightfully ashamed and staring at the floor.
"Why did you bring him home?" Olivia asked clinging to Peter.
"He belongs here, with you." Altivia said. "And the secretary had been lying to us about you."
"Even a blind rat could see that!" Walter snapped, Astrid putting a calming hand on his arm.
"I suppose you're right." Altivia said looking at Walter. "However we were fooled."
"We were told that you were at war with us." Alt-Charlie stated.
"Well we're not, not yet at least." Olivia said feeling Peter running soft circles on her back. "But once Walternate finds out that you brought Peter home he…"
"He won't." Peter said looking down at her. "There was a fight before we came over. Walternate was going to shot me but the other Olivia saved me, she shot and killed him."
"Walternate is dead?" Walter asked and saw Peter nod. "That is wonderful news!"
"Walter." Astrid said a bit surprised at his exclamation.
"My son is safe and home and that bastard is dead!" Walter yelled happily and ran over to Gene to tell her.
"Well he seems happy." Alt-Charlie remarked.
"Yeah though I think he's a bit high." Astrid said and followed Walter.
"What does she mean?" Lincoln asked speaking for the first time since getting there.
"The chances of Walter being on drugs at any given point of the day are pretty high." Peter explained.
"So he's stoned?" Alt-Charlie asked.
"More than likely." Olivia nodded and looked sad since she remembered their Charlie saying something along the same lines.
"I know." Peter said hugging her to him a bit tighter. "It was hard working with him."
"What?" Alt-Charlie asked.
"The Charlie Francis from here…He was close to Olivia and me." Peter explained.
"What happened to him?" Lincoln asked.
"He was killed by one of Walternate's shape shifters." Olivia explained and saw Alt-Charlie pale.
"Well that's not going to happen anymore." Altivia claimed. "The secretary is dead; coronal Broyles is dead as well. No more shape shifters will be sent over as long as I'm alive."
"Why should we trust you?" Olivia asked. "After all you stole my life for two months and lied to everyone that I love."
"Look, I was only doing my job." Altivia shook her head. "I was under the impression that you were just creatures that didn't deserve to live, but when I got here and saw that I was wrong, things changed. Then when I heard the secretary talking to someone saying that there was never a war and that your world was ignorant to the existence of mine…You don't deserve to get killed just for being alive."
"What will you do?" Olivia asked.
"Well Charlie and Lincoln have arrest warrants out on them for blowing up that god awful machine so they might end up in jail for a bit until people realize that the secretary is dead and link the bullets to my gun…so. I don't really know what will happen." Altivia explained. "But whatever happens, we're strong, we'll make it through."
"We could always stay here." Lincoln remarked.
"You maybe, but try and explain two Olivia Dunham's and a seemingly resurrected Charlie Francis." Peter pointed out to Lincoln.
"Yeah that might be hard." Lincoln nodded.
"And we're not leaving you behind." Alt-Charlie pointed out.
"We should go." Altivia stated and looked at the portal behind her before turning to face her double. "Please don't be angry with Peter. I'm the only one you should be angry with. I know that pretending to be you and taking your life was wrong, but you have to understand that I didn't have a choice."
"Did you know that they were going to kill me when I realized who I am?" Olivia asked and saw Altivia shake her head 'no'.
"I didn't know what they had planned for you." Altivia admitted taking a few steps closer to the machine. "However, that's the past now."
"Yes it is." Olivia agreed.
"Don't be angry at Peter for what happened between us." Altivia said getting curious looks from Alt-Charlie and Lincoln.
"I'm not, not anymore." Olivia said and watched Alt-Charlie and Lincoln walk through the portal before Altivia followed, turning to face her.
"Good." She remarked and left. Walter ran over and shut down the machine before covering it up with Astrid's help. While they did that, Peter turned to face Olivia who beamed up at him with tears in her eyes.
"So Rachel knows that you're healthy again?"
"Yes."
"She knows what I did?"
"Yes."
"Is she going to kill me when we go home?"
"More than likely." Olivia smirked.
"Will you marry me?"
"Y…What?" Olivia asked startled.
"I know that I don't have a ring to do this properly but I love you with all of my heart. And after everything that we've been through…I never want to be away from you ever again. So, will you marry me?" Peter explained.
"Yes." Olivia said so softly that he almost didn't hear her. "Yes, I'll marry you."
"We should tell Walter." Peter said and took Olivia's hand leading her through the lab to find Walter who had wondered away again. Both of them ready to put the past behind them in favor of a brighter future.
