As soon as Jack Harkness realizes he can communicate with Castiel anywhere, anytime just by saying his name first, that’s going to be a flirtation game changer.
It’s 3am and Castiel is chasing ghosts with the Winchesters, when suddenly he hears a familiar voice say in his head: “Somebody’s thinking about you right now, hot wings, and how cute you are when you’re angry.”
*ded*
“Jack, my wings are the same temperature as the rest of me, and you cannot see them to determine if you find them attractive or not. I understand this is intended as a ‘pet name,’ but I find it inaccurate. …Also, I was busy.”
“Not so busy that you couldn’t show up in my bedroom to correct me, I noticed.”
“…”
“Plus I bet you taste great with beer and blue cheese dressing.”
“… …”
“See? You ARE cute when you’re angry.”
