Spirit Affinity (Insect Spirits), Bear with me please Options

[Sephiroth]

I'm finalizing a reservist character for a game on the Welcome to the Shadows boards, who is a naga combat face. His stats are mostly done, but I've been giving some consideration to quality choices for him and I was wondering whether it would be worth it from both a mechanical and a roleplaying standpoint for him to have a Spirit Affinity to bugs.

Yes, I know that sounds really really strange. I have neither silliness nor munchkinism in mind with this idea, I assure you (though I suppose Yerameyahu may still accuse me of munchkinry with this anyway (IMG:style_emoticons/default/nyahnyah.gif) ). I will probably elaborate and explain this better when I'm not half-asleep, but the basic idea is a bit like that of the Exchange, where the naga would receive random 'favors' from flesh- and maybe some true-form strangers (as well as one or two flesh form NPCs that have developed a more intimate interest and relationship with him - maybe I'd stat them up as contacts or something)... except that he never actually joined this sort of network or consented to this sort of thing in the first place. The very-alien insect spirits have a bizarre and uncomfortably personal interest in him, he doesn't have any idea why they're so interested in him, and this inexplicable 'generosity' from such amoral and compassionless and generally alien entities is more than a little disconcerting and creepy to him. They won't take no for an answer, and they just refuse to go away and leave him alone. As you can imagine, he walks a fine line in balancing their more often than not unasked-for 'favors' with his entirely reasonable and strong wariness and suspicions that they want to eat his soul nom nom nom.

So, what are you guys' thoughts on this? Under what conditions, if any, would you allow something like this from a PC?
