For a prompt Sastiel, maybe Sam realizing how he feels about Cas and thinks Cas feels the same and just goes for it. I am really loving how bold Sam has been on the show here lately. So yeah the details are up to you but I would love confident!Sam. Thank you! :)
Sastiel + confession from confident!Sam
It’s all there. The signs, that is. Sam can tell. There’s too much there for there not to be something... there. Sam shakes his head. He needs to figure out better ways of thinking about this, after all it’s not like he hasn’t had the time. It’s not like he’s had six years of his life invested in this friendship. He’s had time to figure out Castiel’s likes and dislikes, his food preferences, what each of his subtle gesture means (particularly how his eyes drag across things that interest him).
Let’s just say that Sam is definitely one of those things in the most painfully obvious way. Of course, that distracted gaze was the last thing he noticed. First, it was the way Castiel immediately gravitated toward him (and this was after learning about keeping a polite distance between people, after knowing better for years). Then, it was the way their knees touched when sitting side by side, how he sought physical contact with Sam in the most absent minded ways (touching Sam’s shoulder when he wants to get his attention, moving a piece of hair behind his ear and letting his finger trail down Sam’s cheek briefly, hugging him longer and noticeably harder than he does with anyone else...)Sam knows. He knows deep in his bones there’s something here and no matter what it is, he’s going to find out, nerves be damned.“Hey, Cas...” Sam’s surprised by how strong his voice sounds. He’s surprised that it’s even there, that his question is at the tip of his tongue and ready to tumble off between them on his bed. Castiel, at Sam’s dresser taking something out, responds with a ‘hm?’ without turning around.
“Do you like me? And I don’t mean as a friend. As something... more.” Castiel stiffens noticeably. He shuts the drawer. Sam swallows, throat dry. “Because I can’t be the only one feeling... this. Whatever this is.”
“Sam, I...”
“If I’m out of line, if I’m wrong, I’ll stop, but I don’t-” He takes a deep breath. “I don’t think I am. Am I? Cas?”
Despite his intuition telling him otherwise, there’s a small, very negative part of Sam that’s screaming at him for assuming something this big. How could he just ask something like this? How could he tell anyone what they’re feeling, how could he make things this awkward after becoming as close to Castiel as he is? Signs meant nothing without proof, without explicit knowledge-When Castiel inhales visibly shaken, Sam wonders if he hasn’t ruined the closest thing he’s had in the way of romance in some time.
“All this time and you just figured it out now?”He let’s his breath out, relieved. He nearly laughs. Sam moves around the bed and takes immediate note of how red Castiel’s face it and the fact that he tries to hide it. “Hey, it’s ok-”
“If... if you don’t feel the same-”
“Cas, look at me.”“I’d rather-”“Cas. C’mon.” Reluctantly he turns, blue eyes shyly glancing up then down again with a hint of smile on his lips that Sam can’t help but mirror. “You really think I feel that way?” He asks softly. Castiel huffs a breath. “Who knew you were this shy, Cas-” Sam tilts his chin up just in time to catch the eye roll that makes him laugh and pull Castiel in tighter.
