I was fed up with seeing Jack "dying" again and again. It literally was overkill. He is already from the future. That's he's edge right there, but no! It was all part of what brought him back to life blah, blah, blah.*mini-rant*

It's a given unfortunately. Sure Jack has a soft spot for Gwen, but she really overdid the "make him jealous" side of things. At least we saw that Ianto was the exception to the rule.
