Heartwarming / Kid vs. Kat

• The end of the Christmas episode.
  • To elaborate: Coop wanted to stop his feud with Kat in honor of the holiday (and also to remain on Santa's Nice List). Unfortunately, Kat wasn't interested in playing nice, and the only thing that kept him from wailing on Coop was his total preoccupation with being homesick. Kat spent much of the episode pining over a hologram of his family and trying to get back to his home planet of Kat Nebula. Coop discovers what's upsetting Kat, and eventually comes to sympathize. So on Christmas morning, Millie delivers a present from Coop to Kat: A photograph of Burt, Coop, Millie and Kat. He assured Kat that he was part of the family, even if they didn't get along now and then. And with that they stop their feud for Christmas.
• Dr. K helping Kat and co. get back to Earth, and giving Kat a Big Damn Kiss when he has to leave. Doubles as a Tear Jerker.
  • And in the same episode, Kat Kommander notices Kat firing lasers at Coop when the latter throws him off the ship. This allows the Kommander to grant Kat his job back, sending him back to Earth.
• Coop and Fiona in general are just adorable together.
