Keith reminds his students to submit their club admission forms in by the next day. He ends up sorting them into the Wall Cleanup Club.

At the dodgeball tournament, Keith hears a racket and notices Eren's absence, terrifying the class. Mikasa breaks the terror-stricken situation by reasoning out that Eren went to the bathroom and the commotion is caused by Sasha's fart. Keith tells Sasha she should learn to control herself, before saying that if anyone is caught slacking off, the whole group will be fed to the Titans.

In the tests results day, Keith informs the class about their scores. Calling for Sasha, he chastises her for flunking in the tests, and told her she would be denied lunch if she flunks the makeup tests as well.
