'V' For Vashon: The Patriarch (3) - S5-E11
Character mistake: When Ben talks to the old guy about Spider Brown, Ben says, "Somebody that got rich the past week." The time between the shooting and trial was probably months, not just one week. Spider would have been flashing money right after the hit, and then disappeared.
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.
