Disclaimer: I don't own Fringe, if I did...well Olivia would still be with Peter.
Two months later Olivia was making breakfast when Marilyn came in the kitchen.
"Olivia," Olivia turned to her, "we need to talk."
"What's wrong?"
Marilyn pulled her hands from behind her back and held out a notebook and a whiskey bottle. "You detest alcohol, you swore never to drink it since it nearly killed your father years ago. Why are you drinking?"
Olivia turned off the stove and looked at her mother, "you looked through my things?"
"This notebook, it's a diary of...it has things in it I can't even believe...pyrokinesis...telepathy, growing abilities...Olivia what is going on?"
"We've already been through this, you don't believe me...no one does. What I can do, things I can do are because in my world I was part of a child testing center...things done to me. I'm not from this world and your daughter...you daughter is living my life, hurting the man I love...tricking him and I'm stuck here pretending to be..."
A glass broke and newspaper started to catch fire, Marilyn gasped and looked at her.
"Sorry, when I get angry things happen like that," Olivia went to the paper and placed her hand over the fire.
"Olivia no, you'll burn yourself."
Olivia put her hand in the fire and it instantly disappeared, black ash remained till Olivia stared at it. The newspaper became its original self and Olivia stepped back, moving to the broken glass, she placed her hand over the glass and it immediately began to retain its original shape slowly and without leaving cracks.
"Everything's back the way it was." She moved to Marilyn and grabbed the notebook, "it means my abilities have grown enough for me to complete my task. I'll pack and leave, there's no need for me to stay."
"Wait," Marilyn looked at her as she walked away, Olivia turned back. "You're really not my daughter are you?"
"No I'm not, my name is Olivia Anna Dunham and I'm an FBI Agent. I work Fringe events with my colleague and significant other Peter Bishop and his father Walter Bishop. I have a sister named Rachel and a six year old niece named Ella. My mother died when I was fourteen and my father when I was a child, I shot my stepfather when he hurt me. I live with alone and the last thing I told Peter before he left with my alternate was that I loved him, he doesn't know its not me and I'm hoping when I get back...I can send her back."
"My daughter's name is Olivia Sophie Dunham and I had another daughter named Sarah."
Olivia nodded, "goodbye."
