Midna and Zant's Relationship

[Chevywolf30]

I don't think 'crush' is a really fitting word.

Zant is a thoroughly toxic personality, sociopathic at least, likely borderline personality disorder.
What is possibly likely is that he desired Midna, perhaps as little more than as a display of control, or as an idealised conquest, possibly as others have said as a legitimising aspect for a usurper. It's doubtful than anybody like Zant could actually love anyone beyond his idealised image of them.

I can't see the neck snap as being related to Midna. A personality like Zant would more likely be resentful of being abandoned by Ganondorf rather than anything he might have done to Midna.

I have had thoughts very similar to this! My theory is that he was jealous of her being the heir to the throne of the Twilight Realm so he started a relationship with her not revealing his true intentions, then Midna found out what he was up to and cut off the relationship and that's when Ganon pulled up.
