There was nothing in this universe that would ever separate Jim from Spock again, not even death...

...because he would follow.
Spock knew what he needed to say, with every pound of his heart in his side he knew the words. But could he do it? It would be denying his Vulcan half, but then, his father admitted it in the end, did he not?

Mind settled, Spock squeezed Jim's fingers back.
"Because I love you."
