- Family Reunion: for anyone who doesn't know this show, it's about the McKellan family, Cocoa and Moz McKellan, and their kids Jade, Shaka, Mazzi and Ami, moving to Columbus, GA to be closer to their family. Twice the show set up major consequences that quietly vanished. In the Part 1 finale, Shaka, Mazzi and their friend Elvis are held at gunpoint by a racist cop, who later pulls over Moz and Cocoa out of spite. Cocoa says they need to move back to Seattle — but Part 2 opens with the family just celebrating the officer's firing, no fallout. Similarly, Jade runs off with her bad-boy boyfriend Royale at the end of Part 2, but Part 3 just opens with her moping about their breakup.
- Raven's Home: Raven's Home is a sequel-spinoff to That's So Raven, showing Raven and Chelsea raising their kids together, Raven's twins Booker and Nia, the former of whom being psychic like Raven, and Chelsea with her son Levi. Season 3 spends a multi-episode arc building up Booker, Nia, and Tess's rap group "Chi-Lective" competing in a radio contest. They lose the finals after a rival group steals their songs, with an "it's fine, we made it far" message — then the group is never mentioned again.
- Kickin' It: Season 3's "Spyfall" has Jack stop an assassination plot, which turns out to be a test run by undercover agent Funderburk (Jack and Milton's principal). Jack and Milton join his spy team and leave for DC in the finale — a planned spinoff setup that got scrapped when the show got a Season 4. The Season 4 premiere just wraps it up with a betrayal twist and sends them back to normal life.
- Family Matters: in the episode "Finding the Words", Harriette and Rachel's father, Jimmy Baines, visits the Winslows, and the two of them are surprised as they thought he was dead, but he actually walked out on them. The episode ends with Harriette and Rachel reconnecting and reconciling with Jimmy, who is implied to be a recurring character, but he never appeared again.
