Kaeloo and Pretty try to get Quack Quack and Eugly back together after a bad breakup.
"Let's Play Diplomat of Love" contains the following tropes:
- Bait-and-Switch: When Kaeloo finds out that Mr. Cat has been teaching Stumpy about marital disputes, she tells him that he shouldn't be teaching Stumpy about stuff like that because it's not appropriate for a kid Stumpy's age. Stumpy tells Kaeloo that he watches things that "aren't for kids his age" on the internet all the time. Kaeloo angrily grabs his laptop to see what he's been watching. It turns out that he was looking at knitting tutorials for old ladies.
- Change the Uncomfortable Subject: Kaeloo is hanging out with Pretty and Eugly. Pretty asks Kaeloo to explain her "weird relationship" with Mr. Cat, to which Kaeloo responds by asking Eugly about the book she's reading and then asking where the bathroom is.
- Tempting Fate: Pretty talks about how handsome Mr. Cat is. Moments later, he walks into the room after a bad allergic reaction, with his face completely swollen.
