Sym-Bionic Titan - Season 1 Episode 17 Under The Three Moons

Ilana is homesick, so she joins the Homecoming Dance Committee and creates a Galalunian-themed dance. Meanwhile, General Modula's continued failure to kill the princess is spreading across the galaxy. Modula is approached by an alien who guarantees on his own life that he has a creature that will kill Ilana and crush the Galalunian People's spirit. As our three heroes try to prepare for the dance, Lance and Kristin go a little further in their relationship via a karate bout, but she declines his request to join him at the dance. Issues arise when the Mutraddi arrives just as they depart for the dance. Titan at first fares poorly, as Octus and Ilana are distracted by missing the dance, and making Kimmy cry. However, Lance's lack of concern for their feelings pushes Ilana over the top, and the alien is soundly defeated.
