It's not like she hypnotized him. And he didn't have to communicate with her.
I'd say that proof of feeling he had to communicate with her is telling her he couldn't go on with it and that he got out of the car, when he knew she wanted to him to stay in and die. And I'd also say that proof of being hypnotized is that she was then able to command him back into the car to die when he didn't want to do it - but he did, and he died. What higher definitions of these terms is even possible? So given those proofs, what is all your heart based on?
