Marcus Hiding in Theatre Bathroom was a Death Trap
If any one of us had our wrist or hand cut off by Hoax, usually the 1st thing we would do is try to wash the wounded area. OK, I totally understand that.
However, I'm not sure even in that amount of pain, that I'd ever leave a blood trail for my attacker to track me down and eventually leading to getting slain and killed, the way Marcus allowed himself to be tracked down and eventually killed by a possessed Hoax.
I would have made the quickest EXIT from that theatre possible. I certainly would not waste any time trying to hide from someone who was going to find my blood trail and kill me in the process.
Talk about a Death trap. That was it.
Then again, it seems like no matter what Marcus would have done, who knows what his fate would have been had he tried to leave the theatre.
