- When asked, Rosin replied he considers himself 50% Brandon, 50% Steve out of all the characters. His buzzfeed quiz results said Brenda
- Had Rosin written the series finale of Beverly Hills, 90210, it would have ended when the gang graduated college. Answering the question of who would end up together, Rosin, bearing colleagues Jessica Klein and Steve Wasserman in mind, said:
- I bet you we would have brought Shannen back for a very special episode and she would've got with Dylan – Brenda and Dylan. I think that's the one. Possibly Brandon and Kelly too, they would be the back-up and, if I could do the universe over again, Andrea and Steve, but there'd be no Jesse – no offense
