Baseball is halted by Bow, who tries to capture him with a lasso, but Baseball sneaks away. He runs away with Nickel on his back, but trips over his book and lands on Bow, crushing her.

Baseball votes for Paper, believing his "crazy guy" persona was an impression, not realizing it was a serious psychologicial issue.
In Journey Through Memory Lane (Part 1), Baseball starts off the episode with a throwback quote from the trailer, asking Nickel how he is doing.
