Yosuke returns the devious look with a look of anger. He's been through a lot today and he's not going to let some luggage make it more awful than it's already been. The jostle is enough to get him to freak out, grabbing a hold for dear life as well as he screams.

"Yaaaaaaah! What the hell are you thinking, you homicidal horror! Are you seriously trying to kill both of us?!" He stays on top of The Luggage, and doesn't move. He almost doesn't breathe after he's yelled at it.
