[Erik can't really recall a time when Charles had yelled at him like that, when he'd made the other so angry. He doesn't think he ever has. And he knows now, too, that the lie is pointless. Charles knows the truth.]

Alright, Charles. I'm a monster, a murderer. I don't have a choice. Is that what you want to hear? Are you pleased now? [He turns around, eyes livid.] Why do you have to know everything? Why should I tell you about the things I have to do? I can't refuse him anything!

[His voice is shaking now, and it's a good thing there is no metal around, because he knows that it'd be trembling with all the sadness and the rage he feels just now. Perhaps something worse than that might happen, too. Something might've gone flying, might've hurt the guard outside. Erik refuses to think he could hurt Charles, not physically anyway.

Mentally, however, that's a different story. Erik seems to have become good at hurting Charles that way, he again he hates himself for it. His fists clench, and it's like there's a coil wrapped around his heart now.] I can't refuse. Don't you understand? Don't you know what he'll do to you, to your sister, to Hank and Sean and Alex? I saved your lives by offering myself to him.

I'm trying to protect you. And you don't trust me. [Until the time comes when he can kill Shaw.]
