That girl was brave (I wouldn´t had the courage to ask him anything!)...but it´s obvious due to her voice that she is almost dying of an heartattack. haha
I found it. I feel so accomplished right now. I'm never usually able to find fics I read to long ago... Anyway here's the one I found it's actually a series. archiveofourown.org/series/6088
Rebecca Nix first of all... Dean would probably flip his shit. Lucifer would most likely pressure that towards Sam to get a closer relationship with him once and for all. And Sam, well... Sam would probably be hiding in the corner questioning life about his new knowledge of what the fans do.
I used to not ship Samifer but I can't help but ship it a little bit. I'm more of a Sabriel kind of girl. Though I like the thought of Gabe and Luci fighting over Sam.
I love that some fans can ask stuff like that (as long as they are respectful of course) because I personally could never ask stuff like that! It's nice that the actors of the Supernatural family takes stuff like this with humour.
