Dear Dean,
It's Sammy here. Cas fell asleep and I hope he doesn't mind me writing. I'm sorry Dean. I'm trying very hard to keep him safe and happy. I feel like I'm failing you. He is improving. He is still so skinny.... It's scary. I thought I saw a mark on his arm today... I don't want to say anything just in case. So I'll wait a little even though it's gonna bother me. He's been getting angry so easily lately. It's not him... He's trying. I know he is.
Miss ya big bro.
Love, Bitch.
