Haha, true. I think the Jack character needs Ianto to balance out and get human and care. Ah well. Maybe the reboot will take place after and they'll all be alive again? ;)
Oh, good question. Must have been quite a while. I saw someone mention that he's never let on during any cons or Q&As or anything, and that he must have one of the world's best poker faces.
Much as I hated how it turned out, I have to admit it was still a damn beautiful scene, as death scenes go. I was a little sad that Jack didn't kiss him until after he'd taken his last breath though...
