All I know is what I see in the media and Jack=Torchwood. We'll see.

I don't see him dying, but I am frequently wrong so that probably doesn't mean much, but I can totally see them talking about how 'Jack is Torchwood' this season and then next season going on about how Torchwood has always been about more than one person or a couple of people if they did kill him off even though that's the complete opposite of what they're sayimg now.
