Oh, yay for Sarek/Amanda! I love that pairing so much. And I always have a soft spot for Edith--I rewatched "City" recently and was impressed with how she's presented as so much more than eye candy, she's a visionary and humane woman and you really feel like she's a woman in the wrong time and Kirk's equal. Okay, I also love how she recognizes the bond between Spock and Kirk, too. :)

Scotty/Uhura! I'll admit I didn't much go for Spock/Uhura in the reboot, but not all of it was because it messed up the slash (Reboot K/S does almost nothing for me, as it turns out)--a lot was because it messed with Scotty/Uhura as well (I mean, it doesn't make it impossible, but you know what I mean).
