I like Hatate as she is, but the alternate take is interesting.
I don't mind fanon unless it comes to totally dominate canon, like with Meiling or Alice, but I don't see that with this (yet).
Still, either stalker or shut-in have been Hatate's main Flanderization points among the fandom since she came out, it seems. Just that neither have been depicted with as much depth or as disturbed until now.
