Irene: I know what I want my last words to be. Are you ready?
Des: Yeah.
Irene: There is beauty in the inevitable.

Larissa: I barely even know [Mary]. I mean, I try to be friends with her but she's aloof. Like a cat. That's why it's weird that she lent me her car... but y'know people can surprise you.
Grandma: So can cats.

Mary: Y'know, I've been thinking about Irene. If my family had the gene, I'd want to know.
Des: No, I say wait for the symptoms. In the meantime, eat, shag, and be merry.

Mary: That's beautiful.
Nora: It's true

Des: Aging baby boomers are going to want to die in the same manner in which they lived - bourgeois comfort. Now, the Swiss they know that. That's why death tourism is such a massive business over there.
Mary: And?
Des: And we should be starting to buy up property, getting ready to go legit. I'm serious. I'm having an entrepreneurial seizure here. Let's be a start-up for shutting down. The spa you'll never want to leave. And you won't. If you're travelling the River Styx, why not take a yacht?

Charlie: Does it hurt?
Des: No, it feels lovely.
Charlie: Seriously, I didn't mean to...
Des: ...shoot me?? Yeah, funny that, yet here we are. There's probably a lesson about guns embedded in all of this, eh, Charlie?

Mary: I've been thinking. I really need to quit.
Des: Killing people?
Mary: No. Smoking.
Des: Oh, no, you're right, you should. It's a filthy habit.
Mary: We can't stop helping people.

Des: In a blaze of glory.
Mary: Guess we all gotta go some way.

Mary: Life can get really messed up sometimes and every now and then, it'll just have its way with you.
Jess: What do we do?
