Lol was actually just going to ask if he could. But yeah that's one of the biggest plot holes in my opinion, how could the Animorphs really been that big of a problem to the Yeerks when they had to revolve around a school day schedule. But yeah don't worry in the end Dex was gonna back down either way because he knows he needs help. He just is to stubborn to acknowledge a weaker species giving him orders as acceptable
