Can't wait for Trek XII where the Enterprise intercepts Admiral Archer's beagle. (Sorry...couldn't resist it <g>)
Here are the last two paragraphs in the movie novelization:
No one was in the transporter room when it unexpectedly and fleetingly energized. The figure that emerged on the pad closest to the rest of the chamber did not hesitate, but made straight for the nearest open portal. The blip engendered by its appearance was too transitory and insufficient to alert security. It did not matter, because the unexpected arrival's appearance on board caused only consternation and not alarm.
For the life of them, as it sped outsystem and entered warp space, no one on the Enterprise
could figure out where the beagle with the very peculiar ears had come from.
So, will Scotty keep it or will that make his other pal jealous? I think that should be the main story focus of the sequel.
Star Trek: The Sirius Imperative--coming to a theatre near you.
(is the novel worth the read--I've found Trek movie novelizations hit or miss over the years)
