Kimmy's 30th birthday party isn't quite the fun celebration of adulthood she wants it to be. Titus promised Kimmy that he’d make a song for her, but instead he sings Firework (which Kimmy has never heard before). Logan and Dong get into a fight over Kimmy, which gets physical. Kimmy asks everyone to leave during the party. Kimmy eventually realizes that she had a fun 30th birthday!
