John cannot be of blood type AB if his mother is O as stated in the episode, he can only be A, B or O depending on his fathers genotype. Also his mother should be able to donate since O is the universal donor and they are both Rh negative.

At the end of the episode in Derek's flashback, we see that he is the one who killed Andy Goode, who dies in episode 1x05, Queen's Gambit.
