- Crazy Awesome: There's a reason why Cody became the show's Breakout Character.
- Ensemble Dark Horse:
- Cody Lambert, Frank's nephew. Too bad he gets Put on a Bus in later seasons... His actor was currently dealing with both substance abuse problems and a domestic abuse arrest at the time...
- Al is very popular, because of her cool personality, Character Development, and how She Is All Grown Up in later seasons.
- Flash becomes something of an Ensemble Dark Horse despite his short tenure. His sweet, Adorkable personality probably helped.
- Fan-Preferred Couple: Cody/Dana, though the Official Couple Rich/Dana also has its own fanbase.
- Fridge Logic: Lily Lambert-Foster receiving her mother's late former husband's surname. This was a nice way to resolve a series premise. It symbolizes the successful union of the Fosters and Lamberts as a family, bringing the related plot lines to an end.
- Replacement Scrappy: Jean-Luc, a French stereotype who hits on Carol.
- Retroactive Recognition:
- Patrick Duffy (Frank Lambert) is also best known for playing Bobby Ewing on Dallas and Stephen Logan on The Bold and the Beautiful.

- Strangled by the Red String:
- Dana and Rich. After spending two seasons barely able to stand being in the same room as each other, they suddenly started dating in season six... and still acted like they could barely stand to be in the same room as each other. In some episodes it really bordered on Informed Relationship.
- JT and Sam. After their first meeting, there's a Falling-in-Love Montage showing they have supposedly a lot in common (they both like football, that's it) and JT decides she's the woman of his life. All the other episodes involve them arguing and disagreeing over everything, to the point it falls into No Accounting for Taste.
- Unintentional Period Piece: Especially since it ran from 1991 until 1998.
- Vindicated by Cable: After a disappointing run in syndication, the show spent nine years on ABC Family's schedule and became part of The Hub's schedule shortly before it changed its name to Discovery Family.
