And sick, so shit like this is what happens. I already did my casting of girl!Cas, and now here's girl!Dean.
I have no idea who the first girl is, and I really wish I did. I found her totally by accident. The second is Stacey Oristano. My girl!Dean would be closer to Nameless Girl, with a few features from Stacey.
Expect girl!Sam sometime.
ETA: Girl!Sam has officially kicked me in the face. There are no tall light-brunette actresses who share similar qualities to Jared Padalecki. As Bobby would say, balls.
