I had forgotten about the little shoulder-touch in "Small Worlds," that's an interesting point. Because you would think that Ianto would be so humiliated after "Cyberwoman" that any rekindling of their sexual relationship between Cyberwoman and TKKS would have to have been Jack's initiation. I just can't really imagine why Jack would want to restart a relationship with him, purely sexual or not, after what Ianto did to all of them, even if it wasn't entirely his own fault.

I really wonder if TPTB ever intended to make the show this complex and interesting or if it just happened by accident of their complete inability to follow up a story line. o_O
