Andy and his brother Josh May were werewolves who lived in a cabin in the woods in Black Forest, Colorado. Sometime after the death of their father, Josh began hunting humans, much to the protests of Andy, who believed that it's not what their father would have wanted them to do and refused to hurt people.
Andy chases down Ashley Monroe in the woods, capturing her and threatening that if she tells anyone what happened to her friends, she'll get worse as he uses one of his claws to scar her cheek as a warning.
When Sam and Dean pay a visit to Andy and Josh's cabin to question them about the recent attacks, a nervous Andy tells the brothers that they go out in the woods at night and offers to help. After Sam and Dean leave, Josh begins admonishing Andy for what he told them. Andy defends himself by saying he didn't know what to say, and wouldn't have had to say anything if Josh hadn't killed the girls. When Josh asks why he didn't eat Ashley's heart, Andy tells him he doesn't want to hunt people as it's not what their father would have wanted them to do, which angers Josh. Josh apologizes and promises Andy they won't hunt people anymore, which Andy doesn't believe. Josh assures him he isn't lying, but tells Andy they need to kill Ashley to tie up loose ends.
After getting Ashley back to their cabin, Andy tries to talk with Josh, telling him he doesn't like what they've become and it isn't who they are. Before Josh can go through with killing Ashley, Sam and Dean arrive and the two leave her. As Sam and Dean are walking Ashley out of the cabin, Josh and Andy attack. In the ensuing fight, Andy is able to get Sam's gun and hold him at bay, while Josh wrestles with Dean. When Josh ignores Andy's pleas to stop, Andy fatally shoots Josh with a silver bullet. Andy changes back to human, and tells the Winchesters Josh wasn't going to stop and had become a monster, and tearfully tells them he is a monster too before turning the gun on himself and pulling the trigger.
