does jackson become a werewolf in season 1
Jackson is the big man on campus at Beacon Hills High, and has a competitive, self-absorbed and aggressive nature, which shows through hostility towards people who best him. Jackson wishes to make others proud of him, this desire to always live up to people's expectations appears to stem from his deeply rooted insecurity about his adoption and the fact that he does not know his real parents, leading him to be unable to see his adoptive parents as his true mom and dad. Despite his abrasive character, he is shown to care for his friends and dislikes hurting them. It turns out he is genuine friends with Danny Mahealani and he actually cares more for Lydia Martin than he lets on, though he'd never admit it. During Season 1, Jackson is angered, suspicious by Scott's sudden, seemingly impossible improvement on the lacrosse field and other activities repeatedly besting him, which impacts his psyche. Consequently, he investigates Scott, eventually coming in contact with Derek Hale and being accidentally scratched by Derek in ``Magic Bullet'' (who was poisoned with wolfsbane at the time and partially passes the poisoning onto Jackson through the claws), witnessing the Alpha werewolf in ``Night School''. He eventually discovers Scott is a werewolf. Jackson threatens to expose Scott unless he helps him become one too. The Argents grew suspicious of Jackson. At the school formal he gets drunk and exposes Scott's werewolf nature to them. In the Season 1 finale, ``Code Breaker'', he regrets turning Scott over to the Argents, and helps Scott, Allison and Stiles defeat the Alpha werewolf, Peter Hale. Later Jackson appears the Hale house demanding the Bite from Derek because he helped him.
