Ooooh, introspective Ianto! It's about time he started examining what happened between himself and Paul and accepted that it wasn't just the alcohol.Hopefully by the time he merts Jack again he will have come to terms (as much as is possible) with his sexuality. It's a confusing time for him, and I guess his obsession with Jack isn't exactly helpful, but it's not going away so he'll just have to get used to it.
