Help him out

From Create Your Own Story

You explain what happened to her and you (leaving out that you killed Paul). He takes a amount to sit down but hears what you have to say none the less. You tell him about your ability to control humans and how you mutated. You tell him how you saw the girl dieing and you turned her to save her,(which is a lie but you want to help him and you need his trust so...). He seems happy that zombies fear you. He asks, "How can you help us?"

You say "I can help by..

turning every survivor into my thralls."

or

by helping you kill off zombies and maybe I might even be able to turn zombies in thralls."
