Joseph Misbehaves in Detention / Grounded

After Joseph receives another failing grade on an assignment for plagiarizing, he has to serve after-school detention with Miss Stillwater for an hour. During his detention, he dances and sings to kids songs, and what not. But Miss Stillwater does not like what Joseph is doing, and tells him multiple times to sit down for the rest of his detention. Will she have Joseph serve detention for more time? And how will Joseph behave if he has to do so anyway?
