Everything is still pretty nebulous right now but it’s tending in two drections…for pure dark fic PWP rape/non-con nonsense, Qstiel sees some of Cas’ fantasies and decides to reenact them out of curiosity. For something more plotty, Qstiel returns to earth because if he has to be awake it might as well be FUN and this Dean Winchester (and/or Sam Winchester) person seems mighty interesting…

I mean, they’re all family…what can he make them do for their friend Cas?

If you write either or these, let me know. I’m very into the idea of Qstiel impersonating Cas, though. Just for him to see what he can get them to do, what kinds of lines he can get them to cross just to see how deep these affections go. I’m very into the manipulation. 

Also, just throwing this out there, but Jack is also living with the Winchesters. I wonder what he might do to get approval.
