I was hoping for the same thing; I got excited because I thought they were setting up a sort of mirror to threatening Rhys causing an instant surrender with Gwen by threatening Ianto causing an instant surrender in Jack. But, like you said, no.

It's funny, because I was just today thinking the same thing about Ianto getting under my skin. I went into this show loving Jack, and though he pissed me off I still love him. But Ianto is the one who I just want so badly to be happy. It's strange, because Jack is that character for me also, but only when he's on Doctor Who.

I love Ianto's suits. =D
