All jokes aside, I actually did think of him as a bit racist when he reacted as he had to the fact that his crush turned out to be a shapeshifter in one episode.
If beauty is truly on the inside, what difference should it make if the girl can shapeshift?
Wesley should know human women do the same thing, only they use makeup, wax, and razors to look less like sasquatch.
To Wes' credit, he did seem to kinda
get over it, though to me, it seemed like it was more because he knew she wasn't going to be on the ship much longer anyways, like a bad date that was finally coming to an end.
However, he did find her transporting molecules attractive enough, so maybe beauty is
on the inside!
