One of my favorite scenes in all of Trek is the Spock/Sarek exchange in TVH. Both of them are trying their best to hide their emotions, but it's pretty darn clear that there's a lot of emotion bubbling under that they're both trying to navigate, Sarek in particular. And it's also clear that he's pretty proud of his son and glad to have him back in the world of the living.
I agree, and I have always enjoyed Spock's last words to his father to tell his mother, "He feels fine." It feels so appropriate in their exchange.
