I am quite disappointed with Supernatural's portrayal of werewolves to be completely honest.
However my favorite episode with werewolves on Supernatural is definitely Bitten (Season 8)I just found it just told how it affected these college kids lives.
Also disappointed with who became a werewolf. Like geez. I'm not going to say who for those who havent watch it but yeah. I didn't like it cause they were really useless tbh when there was danger.
