I'll tell you all a secret: Every episode of Star Trek is in its own parallel universe.

Well, by the time the Traveler and Wesley do run off together he is 6 years older...

TOS showed that crewmen have different native languages. I assume the UT is what allows different Earth cultures to keep their own languages. If they were removed, would humans have difficulty understanding one another?

Is it just me, or do I sense the suggestion of a scene between the klingon and human Torres? I wonder if that would help her through some of her issues when she gets reconstituted.
