If you've seen Star Trek IV: The Voyage Home, I'm sure you remember the whales. But before the whales, there was the part where Spock, who is recovering from... well, being dead... has been undergoing some retraining, and is taking a test to make sure everything is back where it's supposed to be in his head. He does quite well on the test, answering question after question -- chemistry, math, physics -- until he reaches the last one. A trick question if ever I saw one. "How do you feel?"
How do you feel?
Well... He'd come back from an attempt at emotion-cleansing on Vulcan to save Earth in the first movie (mind-melding with a dangerous and lonely alien entity in the process), died of radiation poisoning in the second movie while saving the Enterprise and his beloved shipmates, and come back to life and been reconnected with his "katra" in the third movie, as the universe was saved from certain destruction, but the Enterprise met a fiery end, sacrificed to save its crew.
At the moment, everything's good. He's hanging out with his folks, and getting ready to head out in an appropriated ship with all his old friends. He seems to remember math and physics. He's got his soul back. The universe is once again in jeopardy from a whale-singing alien probe, but he doesn't know that yet. Everything's good.
Everything's good. But I don't blame him for not being able to come up with an answer.
What is this apropos of, you might ask?
I don't know. But it was on my mind.
