Reid: That was awkward.
Garcia: Oh, my God. We used to come every year. I can't believe he brought someone else.
Reid: Well, you brought someone else.
Garcia: Yeah, someone I couldn't possibly be sexually attracted to.
Reid: You're welcome?
Garcia: Kevin brought another woman. I'm plotting revenge. Do you want to help?
Rossi: No. Now, you know I love you both, but this is Saturday and it is my day off, so I prefer to love you from afar. So, Have fun! It's my bedtime.
Reid: It's 9 am.
Rossi: (looks at their costumes) You're judging me?
