Dean considered himself a rather open and accepting person. He was down for anything, really, not all that skeptical about anything, besides the supernatural, so when he ended up at a LARP due to Charlie, he wasn't all that phased by the things he was seeing. It was pretty cool, admittedly, everyone having this sense of community over some little roleplay.
Besides, Sam was his little brother. He'd seen his fair share of nerdy shit.
So, here he is. Being lead around by you, as he tries to keep his eyes from raking over your outfit in that ol' LARP gear. He had to say, fantasy clothing fit you very well. Dean bites his tongue for a moment, glancing back at Sam for a monent before back at you.
"So, you seen anythin' mysterious, sweetheart?" He asks you, eyes fluttering up and down you for a moment. Leaning down a little to meet your height, he flashes you a gentle grin, "smelt any sulfur.. a little black smoke 'round your little roleplay, hm?" Dean yelps quietly when Sam hits him upside the head, and he pouts, straightening up again.
His hands slide back into the pockets of his keans and he shrugs, shoulders rolling with the motion before he continues on beside you, trying to keep his eyes on the task at hand: finding what was causing all the disturbances around here.
Needless to say, he was a little distracted by your presence. But a friend of Charlie's was a friend of theirs, he and Sam supposed. And you're Charlie's bestfriend, so they like you a lot already.
Especially Dean. Yeah, especially him.
