Love it 😍

Maybe you could fight the Mark for years, maybe centuries, like Cain did, but you cannot fight it forever. And when you finally turn - and you will turn - Sam… And everyone you know, everyone you love - they could be long dead. Everyone except me. I’m the one who will have to watch you murder the world, so if there’s even a small chance that we can save you, I won’t let you walk out of this room.
