(Castiel is thinking about going to investigate a potential case with Jack...)
Dean Winchester: Just get out there, you know, stay busy.
Castiel: With a murder investigation?
Dean Winchester: Yeah.
Castiel: Sam?
Sam Winchester: Dean's not wrong. And, look, this case, uh, maybe you can help.
Dean Winchester: Alright, well, you guys go "Highway to Heaven" that b*tch.
Jack: I'll get my suit. Can we wear matching ties?
Castiel: Yeah. Blue's a good color on you.
