Stuart: Do you think that I'm wrong for bailing out on the whole "save the universe" thing?
Denise: Doesn't matter what I think. What do you think?
Stuart: It'd be different if I signed up for it. But I didn't, so I don't feel like I'm doing anything wrong. Living my own life, making my own choices.
Denise: Okay.
Stuart: And besides, nothing really happens for hundreds of years.
Denise: True.
Stuart: I mean, sure, there'd be an infinite number of lives lost or never even born across an infinite number of universes. And how's that my problem?
Denise: It most certainly is not.
Stuart: Thank you.
Denise: Unless you want it to be.
