[ season 12 spoilers! ]
sam can’t help but like you. you’re down to earth, intelligent, and don’t back down from a fight. you proved that all when the vampires attacked the men of letters bunker. you aren’t the most practiced with weapons, but you grabbed a machete anyways and accompanied him, mary, and peirce to the weaponry. and when confronted with vampires, you fought by his side.
he could tell your fighting was intuitive, though a little clumsy, but he was impressed when you were able to take down one of the four vamps on your own. and though he wasn’t looking for any praise when he killed the other three, he still appreciated the nod of approval and look of admiration on your face.
“if you’re willing, i definitely wouldn’t mind if you’d teach me a trick or two,” you had said on the way to rejoin with mary and peirce. and so far, you’ve been the kindest to him, despite his slightly bristly attitude. he never got to answer, because the weaponry wasn’t a pretty sight. peirce was gone and his mom was lying on the floor, forehead bloody. you immediately called peirce’s betrayal, and helped him get mary back to standing. walking back, you stood guard in front of them with your machete up.
and then, in the confrontation with the alpha, you were to one to get the bullet to him, subtly taking it from mike, then sending sam the signal and pretending to fight him so he could shoot the alpha.
now, it’s all over, and after talking with mary and dean, he turns back to you, standing a bit off, waiting to give him a goodbye.
you sigh. “that was hardly an advertisement for the british men of letter,” you say, a bit bitter about the losses and mess of the night. “but, believe it or not, sam, we really are–”
“i’m in,” he cuts you off. you give him a look of surprise. “look, tonight was bad, no doubt, but the alpha vampire is dead. and you helped with that. you’re changing the world, and i wanna be a part of it.”
