Diana: Did you kill Gillian?
Matthew: No, I did not. But I should have for betraying you. I spared her life. And I will not make the same mistake again. And I will hunt down anyone who wishes to harm you, and I will kill them. I told you.
Diana: I know you told me. Promise me one thing.
Matthew: Name it.
Diana: You won't go after Satu. I want to deal with her myself.
