It's hard to shake your true nature.

Chloe

As you can see, the Devil does indeed wear Prada.

Dr. Martin: Goodness isn't a toy.
Lucifer: Well, the way I'm going to play with it, it is.

Lucifer: It's funny. I've always looked at do-gooders with pity. Little did I know their dirty secret.
Dr. Martin: And what's that?
Lucifer: It feels good to do good.

One good deed doesn't make you a saint.

Chloe

Bad boy with a heart of gold? I'm everything like Tim.

You had moves that made even the Devil blush.

So you're kissing now? Right. Maybe that explains why you won't have sex with me.

Dan: Okay, Monkey. Surprise. You get to eat chocolate cake in bed tonight.
Trixie: Why?
Dan: Does it matter?

I hate it when people fight over me.

Trixie

I'd really hate to be in your head.

Chloe

Dan: You don't care who you piss off, do you?
Lucifer: Not in the slightest, no.
