Manipulative certainly fits the Jack we were originally sold and while I'd take issue with "dickhead," I'd have no problem with an omni-sexual, actively poly-amorous, flawed human being as the hero of my show.

I'll reiterate that my ships are Jack/Doctor, Jack/Owen, Jack/Anybody but Ianto, and J/I/G. However, if it's pure choice between J/I and J/G, which is some of the fandom feels obliged to frame it, then give me J/G.
