Jeremy goes back to The Park to patch things up with Mordecai, regardless of Chad's warnings. But their buddy buddy time is interrupted when an old enemy wants to get back at Jeremy and even hurts Ioni in the process. (Regular Show had songs in their montages, so while writing about the crossover montage, I thought about listening to the song; "Big city nights" by Scorpions and it fit perfectly with it. While it may be during the day, it transitions to night, making it easier for the song to make sense.)
