Holy FKHASLKJ THIS EPISODE GIVES ME LIFE Sam just actually talked about his feelings about Mary and his grief about never having a relationship with her and his sadness that Dean was always the one she turned to. Sam just actually gave vent to some emotions for the first time in 84 years. Someone hold me.
This is the first time Sam has ever said this out loud. I don’t believe he’s ever admitted it to himself, ever believed himself, until this moment. He’s always thought he was evil… until he saw a boy just like him who wasn’t.
