Fringe, Season 4

Nina:
How are you feeling?

Olivia:
I'm okay. I talked to Walter.

Nina:
What did he say?

Olivia:
Well, it doesn't matter. I met a woman today. She just lost her husband and as she was talking about him and her marriage, as much as she wanted to be, she wasn't in love. As I was listening to her, I realized what she was saying: she had let go of he possibility of love, of finding love, and I could see myself in her. I didn't like who I was. All of these memories and feelings that I'm experiencing, they're from a better version of me. I just decided to let things run their course.

Nina:
No, you've had an emotional day. You don't have to decide anything right now.

Olivia:
I've made my decision.

Nina:
You have so much in your life, Olive. Are you just going to let that all disappear? And be replaced by what? Memories of a life that you didn't live?

Olivia:
Yes.

Nina:
Well, how long do we have?

Olivia:
I don't know. Neither does Walter.

Nina:
Well my mother used to say "encourage the quest for happiness in your children, even if it takes them very far away from you."

Olivia:
When the day comes, if I don't remember this, I want you to try and build something with me again. Don't give up on me. [Nina nods tearfully] I love you, Nina.

Nina:
I love you, Olive.
