Not the same thing, but throughout the scene with Lois in the boardroom, to Ianto handing Jack a gun. it almost felt to me as if Ianto was so pissed off with Jack (over Jack's failures to confide in him) that he intentionally marched to his death.

I guess what I picked up on was meant to be building momentum for the Crowning Moment of Awesome that backfired, so to speak, but really I had a feeling it was just not going to go well all along, and when Ianto told his sister "I love you," I knew he was a goner. And strangely it seemed as if he knew it, too. I think that was odd, because really I can't see what reason he had to think he would die. I dunno. Maybe he just hoped he would. (I know, this makes no sense.)
