1. When he lost control of his emotions
Spock, half Vulcan, was always in control of his emotions. But in "The Naked Time," Spock got all kinds of intoxicated (thanks to Psi-2000 Polywater) and felt all of the emotions he'd been concealing. He cried. A lot. He regretted not telling his mother he loved her when he had the chance: a heartbreaking moment
2. When he told us to live long and prosper
It's a heartfelt wish forever cemented in the pop culture hall of fame. Thank you, Mr. Spock. And thank you, Leonard Nimoy.
3. When Spock and Kirk worked together
This bromance will stand the test of all space and time. Technically it already has.
4. When he saved Captain Pike
In "The Menagerie," Spock risked his station and his life to save his former captain. And it wasn't the last time he put it all on the line for a friend
5. Every time he and McCoy squared off
Spock and McCoy: they fought like an old married couple. But when McCoy suffered from frost bite in the bitter cold in "All Our Yesterdays," Spock refused to leave him behind. Thus, McCoy called him a "stubborn, thick-headed Vulcan." Such a sweet bond.
