Kate Bishop and Castiel
Well, that was a relief. Kate felt a little better dancing with Castiel knowing that his boyfriend wasn't psychotic or something.
"Of course I'd share! Coffee is best when shared." She gave him a warm smile as the song ended, then she took a half-step backward and gave him a curtsey. "I'm really glad that you came to say hello tonight, Castiel. Thank you for the dance. I hope we can have coffee together soon."
