Just wanted to comment on this stand-alone episode. Quite good, tholeans, suliban and the key part of the story, the guy from the future mystery wasn't solved. Some of the best shows are when the NX is outgunned and out numbered, and there is no clean wrap up to the show, it just ends with questions. Those are good ones, not every episode needs to have a happy ending or end where everything is perfect - this ep is a good example.
