The character continued to develop, with Nimoy creating the Vulcan salute during the filming of "Amok Time". This was based on a Jewish Kohen he had seen as a child. During the course of the season, a rift grew between Nimoy and Roddenberry and by the end of the year, they only spoke through formal letters. After the departure of producer Gene L. Coon and the stepping back of Roddenberry during the third season, Nimoy found that the writing of Spock deteriorated. In particular, he did not like the character being made a fool of during the episode "Spock's Brain". The interracial kiss between Kirk and Uhura in "Plato's Stepchildren" had been intended by the writers to be between Spock and Uhura, but Shatner persuaded them to change it.
