after jess — after she died — sam just couldn’t let himself fall in love again.

he couldn’t handle falling for another girl that he’d eventually end up losing in the end.

he just couldn’t handle it.

first, his mom was killed when he was just a baby, and then, his girl, just when he was starting his life in college, which led to him going back to the life of hunting with dean.

and when you came into his life, he was even more determined to lock his walls so high up that there was no chance of ever letting anyone in again to ever risk losing another person in his life again.

so, when you start to fall first, hoping for more, he’s even more and more determined to keep his walls up.

but, when you and sam are left alone during a hunt for a shapeshifter, now in your motel room, you decide that you’ve had enough.

after looking at him for too long with something akin to yearning and longing, sam notices and shakes his head at you. “don’t,”

“we can’t.”

you’re not dissuaded. you’re not giving up.

at this point, you’re willing to test his patience, even if it means having to tempt him with the deep attraction between you, and that’s what you do as you begin to approach him, determined.
