Letters: Kat

Sam didn't want to think what his saying yes would do to his twin. But after seeing Michael take Adam instead of Dean, one of Sam's deepest fears was that Lucifer would get to his sister, and she would say yes to protect him.

He was glad Kat didn't have to see him say yes. Though the night before, he slipped into her truck - Dad's truck before - and put a letter for her in the glove box on top of her phone charger. She would find it eventually, and he hoped that it might give her a bit of peace...
