FFFFFFF. I did this one months ago. I kinda like it (mainly because of Dean/Miranda xD), thought some of you could find it funny.
The two 's' on Cass were intentional to match Mass
Commander Castiel Shepard is trying to avoid the destruction of the galaxy. His partners are Mirandean Lawson, a perfect woman who would do anything to protect her little sister, and Samuel Krios, whose memories are as vivid as real life (if you lick him, you'll have hallucinations).
Mass Effect (c) Bioware
Supernatural (c) Kripke
NOTE: I never intended for this to be a good photomanip. Take this into account xD
