Re: Ships that *never sailed*
I know this would have almost been impossible to carry out in story lines, but I always found Spock/Chapel and intriguing match-up. That scene with the two of them in Amok Time when they are alone in Spock's quarters? Man you could cut the sexual tension with a machete. Clearly you could have had a taste for the human women run in the family too.
Beware the army that marches carrying the Chihuahua before it!
