When
Angel, Micheal,
Burt and
Saul come back and find the place invaded, I think it was Saul that mentioned that his head got blown off. I doubt the tattooed one has or needs a gun. Plus, If he was with
Lizzy, why is it that she made it out and not
Paul? I think he either walked in on her having a conversation with
the mallers or eavesdropped and was found out. Either way, I think Saul or any of them for that matter, would know what a gunshot to the head looks like. That's my opinion...don't eat me :S
