A large group of people go to the pool. At some point, people begin having battles to see who can touch a certain part of their body. This was usually the ear or the stomach. There was also a cannon that sprayed water. If this spray touched you, you would begin to sing very enthusiastically. Dark Pit was notably hit by this.
Later in the episode, Karis tells Embless and Tyrell she has made her choice between them. The two boys sit in their room and wait. They get a slip of paper. It isn't told what it says. However, Embless lowers his head when he reads it, while Tyrell's eyes widen in surprise, so it can be assumed that it said that she chose Tyrell.
"Everyone is battling and singing at the pool."
