Diggle: You really did lose your mind on that island.
Oliver: Found a couple of things along the way.
Diggle: Like what, archery classes?
Oliver: Thank you for coming.
Laurel: I care about the lives of other people, Oliver. Maybe you should try it sometime.
Thea: So why don't you make a play?
Oliver: There are reasons.
Thea: Mm, what are they? Besides you sleeping with her sister and her sister dying and her father hating your guts and you basically being a jerk to everyone since you got back.
Oliver: Those are the top ones.
Joanna: You know, if you go somewhere that's not work or your home, your odds of meeting someone increase by, like, a gazillion percent.
Laurel: Oh, that's not true. I could still get mugged on the way home.
Joanna: In that case, I hope he's cute and single.
