Morty and Mary in “Unfinished Business”

Morty

Mary, I need you to do something for me.

Mary

What? I'll do anything.

Morty

I need you to go see your mother.

Mary

I can't.

Morty

You can't or you won't?

Mary

Both. She disappeared from my life when I was ten years old, Morty. Gone. This whole time I've thought she's dead.

Morty

But she's not. You get a second chance, kid. Other people aren't so lucky. I'd give everything I own to have a second chance.

Mary

What are you talking about?

Morty

Zoe Anne Sapperstein. My only daughter.

Mary

You had a daughter, Morty? I didn't know you had a daughter.

Morty

Yeah. We got into a fight over this boy she was seeing. Her mother and I disapproved. She left college and took off for San Francisco with the guy. We didn't speak for years. One day the phone rang. It was the Highway Patrol. Carpet salesman from Oakland had too much to drink. He fell asleep behind the wheel and hit my daughter's car. Killed her instantly. Not a day goes by I don't wish I'd picked up the phone and called her. I let the privilege of knowing her slip away because I was a stubborn SOB. Don't make the same mistake. Put away your anger. Go see your mother. You only have one family.
