TRICK OR TREAT, MOFOS

First of all, I am SO FREAKING SORRY THIS IS SO LATE.
A ten page paper on Renaissance menswear was due. D:

But this is here now, and it's a Halloween art exchange for the #All-Things-Holy club on dA. This one is for *Shadowcat2503, who requested the boys all ready to infiltrate a Halloween party dressed up in costume.

Obviously Dean is Batman, the Dark Knight.
Therefore Castiel is Robin, the Boy Angel Wonder.
And Sammy is Nightwing, angst-whore extraordinaire.

Taking Cas trick-or-treating must be like trick-or-treating with Charlie Brown. He only ever gets rocks. D:
