AU [based on “The Hangover” movie]: Sam and Jessica are about to get married. Two days before the wedding, Sam, Dean and Cas drive to Las Vegas for a bachelor party they’ll never forget. But, as it turns out, the next day they don’t remember a thing and Sam is nowhere to be found. But they find out other interesting things instead.

“What happened?”
“I’m not sure, I don’t remember much.”
“And why the hell I have a wedding ring on my finger?!”
“I believe we got married.”
“What?”
“I have the same ring and I found in my pocket our… wedding picture. We looked happy.”
“Okay, I have a fucking headache. We’re gonna talk about this later. Now, we need to find Sam. Jess is gonna kill me!”
