Re: Who is John Harrison (Possible SPOILERS or Insane Babbling)
I think he's a new character. It would be the most interesting option to me. I've said it before, I'll say it again - why would I want to see a story I've seen before retold with different actors? Why would they go to the trouble of rebooting an entire universe to retell a story that's already been told?
Pain or damage don't end the world. Or despair, or fucking beatings. The world ends when you're dead. Until then, you got more punishment in store. Stand it like a man... and give some back.
