User blog comment:WoodZillaTV/Why do you think Jackson isn't turning into a Werewolf./@comment-4832985-20120625171318

personally, i dont think hes turning because, in the episode Magic Bullet, Derek stuck his claws into Jacksons neck, and he was being poisoned by wolfsbane at the time, and after all the trouble hes been having with the mark, that can be causing him not to change.
