I was watching Star Trek IV: The Voyage Home just the other day. As much as I love the theme of the movie, save the whales and all that, there was one thing that really bugged me about Dr Gillian Taylor, the cetacean expert who was director of the Cetacean Institute.
After the initial shock of learning that Admiral Kirk was from the future and has come back in time to “repopulate the species”, she decides to jump into his trasporter beam and hitch a ride back to the 23rd century, reasoning that the future would need somebody who actually knew something about humpback whales.
Fair point. Who in the 23rd century would know anything about humpback whales. So, a little while later, as Kirk and co are getting thier arse’s chewed about disobeying orders, stealing Federation property and destroying said property, our friend Dr Taylor jumps out of the stalls and informs Kirk that she has her own ship to go to, a science vessel, where she has 300 years of catch up learning.
So what about the bloody whales?, they going with her? I doubt it. So now she has landed in a time of luxury, where she wants for nothing, she abandons those poor whales in the sea’s of 23rd century Earth, hoping they can rear that calf Gracie was carrying.
Earth is home to a number of different alien species, it stands to reason that some alien aquatic life now lives in the oceans, some that may carry diseases that could affect those whales with no one on hand to check if thier doing ok. Sounds like Kirk marooning Khan and not bothering to check on his progress.
Also you’ll notice that as Gill moves forward 300 years, she gets a nice new uniform to wear, but her hairstyle stays the same. Guess she was lucky that the bouffant was back in around 2286.
