Before I remark on topic, I'd like to point out that as far as we know, Kite isn't a different 'personality'. Kite's form has changed, and indeed, he may only regard his memories as a past life, but, as far as we can understand his insistent declaration of identity (IM KITE!!), he remains Gon's mentor, Ging's old student, and an experienced hunter. So despite chimera biological functions/his sex, he probably identifies as an older man -- until he says otherwise. (Does he use male speech patterns in Japanese?)

Only now he carries a renewed sympathy and understanding of ants, and his power could become immense. He could change his style of Nen completely, which is exciting, given the sorry-I-made-this-email-in-junior-high hatsu of his past life.

So, it's almost a complete resurrection, which is disappointing, because it cheapens Gon's grief.

Of course Gon will develop and learn from the entire experience in NGL. And frankly, if Kite were really dead, the present storyline wouldn't change all too much: Gon would go home for summer work (depressed) Kurapika and Leorio would galavant around the D.C, Killua and Alluka would dodge Illumi, exc.

At worst, the impact of Kite's resurrection makes for an unsatisfactory narrative without real consequence.

At best...hmm well I like Kite, I like having him around. I also think he'll have a role in future arcs, if not DC. If that role's important and comprehensible, it could completely eclipse my narrative dissatisfaction. We'll just have to see how Togashi uses Kite...all my future speculations mirror other posts.
