If S1 Jack was too distant from his team, S2 Jack is too clingy. It's a logical pendulum-swing reaction considering what Jack went through on the Valiant, but it will be nice to see him get past this issue. It must be said that his team is handling his clinginess very well....And Ianto shows no sign of considering Jack's clinginess to Gwen or Owen as a threat to his own relationship with Jack.

Finally, someone who sees it that way aside from me! :) I don't honestly think that it's Jack in love with Gwen, any more than he was in love with Rose. I think both women believed in him and didn't put up with his crap, and he cherishes that. And yeah, he's being clingy. I have to assume that the Master killed his team in that year that never was.
