However, if his HP isn't regenerating naturally, there's also a high chance (in theory) that he won't revive, then either.

I wonder if Misa's arm has anything to do with his recovery. The summary didn't point out the arm being with him at the moment. It'd also explain why he's carrying it around with him everywhere when we next see him.
