I've been reading reports from the Rift as well. And I agree with you. I love that it doesn't both Gareth or James to be asked questions of a sexual nature for their characters. Hell, they practically insist on it. Have you seen the clip of Gareth saying "Captain sandwich with Ianto filling" yet?
And I love them all the more because they genuinely seem to like their fans. Such a difference from some cons that I've gone to where the actors made no attempt to chat anyone up and looked like they would rather have pins in their eyes than be there.
