You thought you could trust him. And he broke that. What makes you trust this guy? Is it the fact he's an adult? Is it the fact he gave you a kind smile? The fact he saved you?

Every good villain knows tons about the hero's life. You know why? Because every good villain-
Was apart of the hero's life.
They were someone the hero trusted. Someone they knew. Someone they thought was helping them. And we all know what happens. So what makes you trust this man? When all others have been so mean, and even he himself was very rude to you at first, you choose to at least give him a small chance.

You're kind, I'll give you that. But you should know better. And that's something you know very well. The mind is powerful, yet your will is pushing it aside.

If nothing else, your being stupid. And you know damn well.
