It's been driving me insane all day. I cannot remember where I have this from, but I think it's from a movie or a television show.
I remember the scene playing out very quietly but intense; Breaking Bad reminded me of it (watched the new episode today), but I don't think it's from there.
Two people (can't remember if they're men, women or one of each) are in a bathroom (I think). They each suspect the other is wearing a wire, and to be sure they get undressed, turn on the shower (I think) and have a conversation about a secret they share - probably something illegal.
Probably from a thriller.
Anyone got anything?
