I don't know....I just wanted to draw this...
Cas crying blood.....I guess... it's like present time and when he gets his scar (becoming blind in his left eye in the process) at the same time... Maybe it's him having a flashback and imagining it reoccurring.
I tried to show his ribs showing because he's so thin but I'm not sure if it worked out...
I tried to keep the blood to minimum
