Not sure if this question get's asked a lot but it was something I was curious about after watching the episode last night. I know they wanted a more vibrant captain which explains bringing in Shatner and they wanted to keep Nimoy, but what about the other members of the cast. I'm talking of course mainly about Susan Oliver's character, Dr. Boyce, and the helmsman. I really liked Dr. Boyce and that scene in Pike's quarters really getting into how Pike was feeling and Susan Oliver's character was kinda attractive. Why didn't they keep these characters around or at least find a way to bring them back.
