I thought it was cute :D but some people saw it as Ianto *desperately* trying to get Jack's attention. I don't know why people see Ianto as such a puppy-dog, he's a (very intelligent) grown man.

Because that's what they would have done. But they're not Ianto.

Neither can I. Jack may be attracted to Gwen, but if he *really* wanted her would have had done a lot more than flirting by now.

If he wanted her he could have had her by Ghost Machine if not before. "Go home to your boyfriend, Gwen Cooper."
