Hitch Trailblazer is meant to be kind and diligent, not jumpy and paranoid. Can he be uncomfortable about Earth Pony magic and feel out of his element with it not operating off any known rules? Sure, that falls in line with his character well enough, but certainly not to the degree we saw in the episode.TDistrusting magic to that degree and completely ignoring his friends doesn't line up with his characterization from the latter part of the movie or said movie's promotional material.
I'd sooner believe he was bewitched by Opaline to push his thoughts in that direction, except if that was in the script we would've seen her scrying on Hitch and using a weak bit of her magic on him through the scrying pool at the start of the episode.
