But have you not heard? The plot outline for the next film is out, and yes indeed Matthew Goode is cast! From what i hear, he will be playing a quasi-omnipotent alien creature separated from it's own continuum by the black hole at the end of ST11, who takes the form of a ridiculously good-looking human as it/he recuperates on board the enterprise. Curious about these creatures, he endeavors to experience life as a human to the fullest, which for cinematic reasons means having lots and lots of sex with all the members of the crew, especially scotty (who teaches him about human humour), bones (he's more of a man-whore than you'd think) and chekov (he's shiny!).
The only exception is spock, because as a highly empathetic and telepathic being the weight of spocks grief hits him like a sledgehammer whenever they are near each other, and Uhura cos she's got spock, and lets face it even matthew goode isn't quite good enough to divert her attention. Which leaves space for S/U awkward sex in the captains chair and lots of beautiful quiet moments in turbolifts.
Oh yeah, and there like some disaster that's wrecking the universe but they're all to busy with their cross-species sexin's to notice so they all die. (Their contracts ran out and the studio is cheap.)
