odd see Vorik for first time Neelix worried his usefulness is over on ship
Despite being on Voyager for a long time, Mr. Neelix is apparently very insecure and worried that now that the ship is about to enter into space about which he's totally unfamiliar, they'll no longer want him*. So he decides that the proper course of action is to make himself invaluable by learning some important skills needed on the ship. This proves to be a waste of time (after all he IS Neelix) and so his plan is to buy a map of the upcoming portion of space where the ship is headed....but it ends up leading to LOTS of complications when Neelix relies on an old friend to help him get the map.
This episode is odd because Mr. Vorik, the Vulcan, is seen for the first time. So you are expected to believe that after three seasons you just haven't seen him before. Yeah, right. Despite this, the episode is interesting and is worth seeing.
*I never liked Neelix very much. Aside from him killing a traitorous crewman, he mostly is just rather annoying. It's just my opinion.
