Spock had once admitted to him that he had experimented with lessening his emotional control in his early years serving under Captain Pike.

I'm particularly fond of this line. It always bugged me that there's no mention of Spock being blatantly emotional in the transmitted story in "Menagerie" (gods, that almost childish glee over a plant, so cute). I mean, I know that it's the first pilot and Spock was practically a human with pointed ears and eyebrows, and that Number One was the logical one. Still, I think they should have done something with that.

Off to read the rest.
