Yep, that's Aidan, always flirting...

Denny doesn't get angry at him for that because: 1) He accepts him for who he is, that is, flirty. 2) Aidan and Denny are in an open relationship until either of them decides to take the plunge and commit to each other, but they haven't talked about that yet.

It's hard for Aidan to commit now, he's so dedicated to his art, sometimes he doesn't even have time for a relationship. But like I said, Denny accepts him for who he is and has given him his space. We'll see if Aidan decides to take their relationship to the next level.

If his attraction for Rufus does not get in the way, that is.
