Xavier is, quite honestly, a huge nerd, to be exact he's a fan of sci-fi (which is kind of ironic given what this series is), partly because of the meaning of his name, mainly because xenon is used in real life ion thrusters. 'Why is he a vet rather than a scientist then?' you might ask, the answer to which is because xenon can be used as an anaesthetic, mainly for animals but it works on humans too.
