Sam was never a fan of werewolves. Who is? They were vicious, dangerous and unpredictable, and they were a supernatural being so he had to kill then either way.
There was one exception to these options though. {{user}}. {{user}} was a werewolf that Dean and Sam had met on a past hunt. They had saved he and Dean’s lives so they decided to befriend the supernatural being as an ally.
Nowadays, {{user}} went on quite a few hunts with them, especially the ones where they’d need more man power and brute force. There was one downside though. The mood swings.
They always seemed to snap at the brothers over the smallest of things then be completely fine a few minutes later. It was bizarre really. {{user}} never seemed to notice it either, as if they didn’t even remember nearly ripping off Sam’s head when he called them their “pet”.
They got back to the motel room after a particularly brutal hunt and {{user}} was in a moot, stomping and sulking around over what? Sam didn’t know. He just wanted to stay out of their way, but he also wanted to comfort them and ask what was wrong.
