In the revival, Dexter tells Slater that it must’ve been hard for him to navigate being Latinx in high school.
The original Saved by the Bell was diverse in a sea of shows that weren’t, but Slater’s Mexican-American background never came up until Saved by the Bell: The College Years, at which point Zack dismissed it because he’d always thought that Slater was Italian.
Slater thanked him for saying that because no one ever brings that up.
