Amaterasu is agreeing with you on this; don't laugh at your human Dad otherwise you might not be awake for very long. You do want to stay around, right?

Yukiko on the other hand is mentally scolding her persona as she and Yu get on the motorcycle to knock it off and keep an eye on the poisoned one and attack any bugs that get in the way...if she doesn't roll over them. Starting the bike was easy enough but driving fast enough to not make the hurt person more hurt?

Little hard.
