"and that's enough, Makoto" Hajime said

"--you're being rather ridiculous" Makoto said, finishing the sentence she thought she was right in the middle of saying.

"No! Makoto, you were barking like a dog until he told you to stop!" Ann protested.

"Ann..." Makoto sighed "So what are you saying? That I'm already hypnotized or something?"

"That's... Actually... Maybe?" Ann said thoughtfully.

He saw Makoto realize that maybe what Ann was saying wasn't so crazy after all. So he stepped in.

"It's fine to think the other person is hypnotized, but if either of you believe you yourself are hypnotized, you will feel the thought being scrubbed from your mind, like your brain being cleaned. And until the thought is scrubbed away, your eyes will roll up and your tongue will lull out" he said.

Makoto immediately slumped forward, her eyes rolling so far back only the whites were visible. Her mouth dropped open and her tongue came rolling forward, as she started drooling on the table

After a moment she sat upright, returning to normal

"Nng... Sorry. What were you saying, Ann?" Makoto asked, as Ann looked at her with stunned silence.
