Will we ever talk about how Spock’s palm initially just holds McCoy by the neck and cheekbones—with his fingers in a standard position—but the gesture gradually shifts into the one we all recognize? Vulcan hand gestures don’t always signify a kiss; it depends on the context, but... We all know Spock kissed that Romulan female commander that way. In other words, an emotionally unstable Spock initially grabbed McCoy intending to lash out, but ended up kissing him instead. And it’s all because his emotions are chaotic: he starts doing one thing but finishes by doing another.
Spock is kissing
However, one shouldn't confuse them; although this gesture closely resembles the "LLAP" greeting and farewell, they convey different messages, serve different purposes, involve different techniques, and—of course—occur in completely different contexts.
Spock Bids Farewell to His Brothers
Actually, Spock and McCoy are constantly kissing in the original series. Well, or trying to.
An attempt at a final kiss before McCoy dies. Look at the positioning of the fingers—it bears a striking resemblance to the way Sarek and Amanda kissed. It is as if McCoy wants to reach out and return Spock’s kiss properly, but lacks the strength to do so.
And there’s no need to even mention that kiss—everyone knows that moment. We all squealed like bitches when we first saw it.
