This may or may not be the man either Larry Mollin or Rosin mentioned in interviews as Spelling having a grudge against Shannen for introducing her to, who was allegedly abusive.
Several of the Heights people got other Spelling jobs when it went under. Cheryl Pollak [sic] went on to play Susan, Alison's college friend who dated Billy on Melrose Season 3. I liked her and she had a great look, but looking back recently I'm not sure if she was much of an actress.
God, I'd forgotten all about Joe. I still can't understand how that went on so long. It seems like an Aaron choice.
Vincent Young was hired off a hit series of Pepsi commercials or something, IIRC, and was their nth attempt to clone Dylan. He was not much of an actor, was locked off to Donna's story, and when Dylan returned he was rendered completely superfluous. I seem to remember by the end he was off in some C-plot with Josie Davis or something, but I barely watched any of the last two seasons.
