The shooting at the complex? There's going to be a lot more things like that happening soon. They'll be like rats trapped in their little hole, and that's just the beginning. Our end game is to isolate Sam, and you've got no reason to trust him or to care what happens to him. No reason to care what happens to the "friends" who locked you up.
You've been a free agent for a while now Ava, but this war is going to make that impossible eventually. At least on our side everyone is motivated by self-interest and we all know it. You can be against the end of the world, but still on our side. You can't drink demon blood and be on theirs. And when I kill Ruby? I want someone who's loyalty is to me not the horsemen
When things start really shaking loose I'm offering protection and blood in exchange for backup support and your promise not to use your whammy on any of my demons.
