I don't know how it will be explained but I assume Adam/Kensei suffered immense pain and destruction from the blast - remember Claire in company man? She was all black and charred for a few minutes and gradually regenerated. This could have taken a few months or years for Adam to 'grow back' if he had to say, grow a new body from his head o_0'' *hates thinking about it*

I also think he will have an edge in that, over the 400 years, he has a higher pain tolerance (ie claire mentioned she still feels SOME pain) and he is not as easily hurt. I wonder if, due to so many injuries, it affects his nerves in someway? So that he doesnt RESPOND to pain. Sorry going off topic. Anyway you saw Peter blast the lightening and instantly the hand charred and healed. I think Adam's healing is VERY fast.

So in short, after 400 years:
-Adam's healing is faster
-He tolerates pain more


What a baddie. How can they kill him? Can he still drown, like if you sank him underwater would he be able to like breathe? I assume since nothing is being damaged or deteriorating, he cant really heal can he?

Or, I dunno, jus bury him alive *shrug*
