I assume that the next in line was Keenser and he left with Scotty. For me, I liked the use of the line. I think it actually works better with Spock. They built up the idea that Spock was suppressing his emotions more than usual due to losing his mother and planet. He lost Pike and felt his emotions as he died. Then he loses his friend, a man willing to risk his career to save him. A man who he knows is supposed to be his friend and that the two are supposed to share a destiny and achieve greatness together. In that moment, he lost it all and all that control breaks down. That is Spock getting pissed and I thought was extremely well done.
