At least we will always have a class 3 Nebula?!
27 August 2016 | by See all my reviews

Good episode to a point. Been going through watching 'Voyager' recently as I never saw the last few series in my initial viewing some years back. We, my sister and I, always thought 'v'ger' As we called it, was the weaker of the 'Treks' - But I'm quite enjoying them and think I was a bit harsh in my, many years earlier views... Anywhoo..

This episode was rather an odd ball one. Usually unflappable Ensign Kim - who after many heroics is still an Ensign... fall head over heals for a very pretty Alien engineer - They are found hanging out at what looks like her college dorm room at the beginning of the episode... Now Star Fleet has some proper regs about new aliens and whether one should get too familiar without medical advice etc but ya know 'feelings' etc - so all are sort of right as they go along - the Captain the Medical issues etc.. And Harry makes a big song and dance about his Alien lady... However the episode falls apart at the end, utterly and totally. After all the histrionics and Alien Engineer Tal gets her wish to leave her family ship - well she rather stay with here group of travellers then consider asking to go with Kim. And then we have Straight lased Ensign Kim who breaks regs for the women he loves so deeply etc - but he doesn't ask to go with her - nor does he ask her to go with him.... Bizarre... What? Does Kim think himself a Capi-tan Kirk, all of a sudden?? Anomalous episode! - surprisingly 'Seven' was able to unravel the malarkey to get a useful life lesson - lesser mortals like myself are still perplexed.
