Scott became whole (physically, anyway) before Alejandro because lacerations and suchlike heal faster than burns. As for Gollum-Zeke, he probably has some kind of mutant healing factor now.

Of course, all this is really just overanalyzing. Cartoon characters can never receive lasting harm unless it's a plot point (or, in Zeke's case, a throwaway gag) that they must.
