"Bill [Shatner] was very upset when Leonard came on particularly strong at the beginning [of the series] because he said, "Am I not the Captain? How come [the writers] don't appreciate that?" It was a very natural reaction. I said to Shatner, "If we had an Eskimo as a second character, you could be sure the Eskimo would get the most delightful lines because of what he is." I advised him not to worry about Spock because all that reflected on Shatner, particularly if Shatner continued to treat Spock properly in the show. I suggested they should show each other a lot of friendship in the show and it would eventually right itself. And, indeed, it did eventually right itself."
