Funnily enough, I don't even really ship them to any great extent, I just get fed up with the inconsistent storytelling in Who and TW sometimes.

Infodumping's pretty bad. I don't care where Ianto sticks that hockey stick, or indeed which end of it, but infodumping exposition on each other I think is something they should try to do in private. The Hub isn't the place for that sort of thing, it makes a godawful mess.
