[Creepy and wrong is just about how Jack's feeling about it all too, and if Kitty had gone for Ianto, well. He wouldn't have tried to hold her back. It's all he can do to keep his sick revulsion contained, but he has to, because who else is going to sort this out?
Watching Ianto enter their flat as if it's the first time he's seen it is incredibly unnerving too, and so is the way he plants his back solidly against the door. Jack lets him, for the moment, because frankly Ianto's not going anywhere, not with him and Kitty there. He faces up to him, arms crossed across his chest, doing his best to shove down his shock and horror to deal with this sanely.]
We all have stressful jobs, yes, and we all have coping mechanisms. But no-one else goes out and kills people to do it, except Suzie and I killed her for that. Twice. [Because nothing is ever simple at Torchwood.
And, because he Jack and he never can leave things alone:] And what do you mean, especially me?
