After a bio-lab alchemy mishap, Spock and Leonard accidentally swap bodies. Such absurdity that it should be them; they weren't considered the demonic duo of the Enterprise because of their close buddy friendship. They both expect all hell to break loose. But what an inconvenience it is, being shoved into each other's brains. Because what are you supposed to do once you learn the little things--things you wouldn't of ever expected--about the man you've feuded with since meeting? And what, in God's name, are you supposed to do with the love that come with them?
