This is the one that got me. Right in the gut.
We rewatched "Yesteryear" tonight. It's the best of the animated Star Trek, quite fine on any terms, and entirely about Spock. It's also where D.C. Fontana wrote that the Vulcan philosophy that a death is to be mourned with tears only if the life that ended had been wasted. I don't think this one was.

Not to mention that he absolutely, positively, stuck the ending.
Well done, Mr. Nimoy. Thank you.
