Noticed something I previously overlooked...

I was on another site - not that one! ;) - and I saw a screen shot of the scene where MOC wearing Dean was staring in the mirror before he went into his "tear up your room like you're a rock star" rage. When I first saw this episode I did see the window in the door in back of Dean formed a cross from the light shining thru. What I never caught until now is that there were two windows! The cool thing is one was dark and the other light. As in the good and the bad are warring inside Dean or that the darkness is taking over his light. I thought the single "cross" was an interesting touch but to see both? I just thought it was a really awesome touch. Gotta love all the crew who work so hard on the show.
