i have no download yet, and i haven't read any spoilers.
Repeat: I am unspoiled! But here is a speculative theory, for the record.
Suppose this regrown Jack is mortal after all because he's not the original Jack that was brought back to life? (It shouldn't work, because he's been incinerated before, but there you go. If they're looking for a way to kill him and end the show, that could be it.)
[eta: Though I confess,
gblvr's icon makes me glad this isn't the first suspicion I've had that Ianto's going to buy it, because I've had a little while now to begin getting used to that idea - the hour remaining in the download I have now found wouldn't be long enough for that. :-P ("Die of old age" indeed, young man. Oh, god.)]
In fact, because I don't want anyone to tell me if I'm right, I'ma go ahead and disable comments.
