I'm rewatching Castle in this Heat Wave (get it? 😁) and I just love this exchange from season 2 episode 6, which aired in 2009. The Firefly movie is from 2005.
Alexis: Hey.
Castle: Hey. I was … I was just … trying on my Halloween costume.
Alexis: What exactly are you supposed to be?
Castle: Space cowboy!
Alexis: Ok. A: there are no cows in space. B: didn't you wear that like five years ago?
Castle: So?
Alexis: So, don't you think you should move on?
Castle: I like it.
