The photograph from Supernatural 5x10 : Abandon All Hope.
After such a brilliant episode, I *had* to have this image as my wallpaper. RIP to two fantastic characters.
Also... Castiel is awesome. Fact.
If anyone wants this as their desktop, just be advised it's better as 'centre' instead of 'stretch' or 'tile', due to the limited pixels of the image. Feel free to take it
