Your boyfriend is Spike? [A low whistle] Okay, I didn't see that one coming. I mean, I know you and he were... black-banded [A quick grin for the euphemism] but I never... Well. Congratulations!
[And that's one couple he definitely won't be suggesting a double date with. He's not sure if Ianto and Spike have met yet, but he'd never ask Ianto to put up with someone who looks like John Hart, and that's just for starters!]
