"He was upset that he wasn't asked to be a part of the reboot, but he talked to one of the executive producers about possibly coming to appear on the second season and he was happy about that," the actor's longtime manager, Roger Paul, tells People. Meanwhile, Mark-Paul Gosselaar discussed Diamond's death with Tamron Hall today, saying: "It’s always tough when someone passes away. I think it’s even more so when the individual is someone you know, and the age of Dustin. It was only a few weeks ago that we heard about his diagnosis, and for it to happen so quickly is shocking." Gosselaar said the Saved by the Bell cast plans to get together to remember Diamond.
