So this is by far my favorite episode.... This week that is. I think it blends dealing with disease spreading over the enterprise with a totally separate issue with the planet bring the ship down. I think it makes for a great episode.
One thing has always puzzled me tho....
When they go back in time the three days... What happens? Do they just hang low and wait three days to pass... go back and save the crewman that died?
Why not go back and Prevent the whole problems in the first place
