Continuity mistake: 7-1 "The Young Assassins": The hotel towel draped over the first victim's beach chair instantly changes positions between shots. You can see the words "Aloha, Hawaii" emblazoned on it, until the shot changes. Then it's moved up, and only the word "Hawaii" and the hotel's logo are showing. (00:01:50)
Visible crew/equipment: 7-1 "The Young Assassins": The People's Attack Group van speeds past the camera and briefly captures the reflections of several film crew members. (00:35:05)
Answer: He was fired. He never really appreciated his character. He felt Kono was portrayed as a big dumb Hawaiian and that the stereotype was racist. He also felt underutilized. He was fired after a heated argument with the show's publicist regarding his character. It seems there's not much details given regarding the incident or the firing, so it's seems possible he upset the show's producers as well.

No he said something derogatory about one of the Jewish producers that's why he was fired.
