i wanna point out that cas was REALLY worried for sam in this episode. in this fandom we usually talk about cas and dean's relationship and always forget that sam and cas are friends too, they're family and they love each other as brothers.
Those tags are soul crushing. <-- I can't breathe right now.because this is the truth. What a parent gives up for their child. It's what Dean had to do. That's how Sam ended up in college because Dean strove to give him that normal life.
