As far as why Malcolm didn't age/die I believe that when he switched with Henry, it was his last chance, and since his kid body was trapped in Pandora's Box until released in SB, from that point on it was safe from Neverland's Magic's end. After that, seeing as they left Neverland, and magic works differently in the LWM, it makes sense to me that he continued being a kid/didn't change back.

How he gets magic we don't know, but I'm sure that will be revealed.
