I hate the accelerated healing fanon thing so, so, much.

He got punched by Ianto and that wound lasted. He got shot and killed in End of Days and came back obviously hurt. When Abaddon killed him he looked like shit after he got up (but no more bullet holes, admittedly). He stands up, groaning after Cyberwoman. After he got killed on Satellite Five he was staggering.

Now, admittedly he had the bullet hole from being shot by Suzie kind of remarkably and magically heal in seconds, but this leads me to believe that the injury that kills him will get healed to keep him from staying dead - but only just. It also makes me think Suzie's the fluke, and honestly with a hole still in his brain he shouldn't have popped back up after that one.

There is nothing in the world that should keep TW_Jack from being hurt and staying hurt. Darn it.
