[desperate, he tries to think of something he can say to help the situation. he knows he's in danger, but he can't drop from the Plane--not when Jamie's holding him] Look, I'm sorry. Just, if you don't want me to--ack! [as Jamie wraps his fingers into his hair, Oliver makes a last attempt to pull away. but it's too late. he cries out] Stop!

[and at those words, his blood runs cold. he stops struggling] Wh-what? What are you doing!? I don't understand!
