Sora's Parents
The journey you undergo in Kingdom Hearts as Sora is all fine and dandy, but imagine it from his parents perspective. One day your son goes missing, and that's the last time you ever see him. The first time your hear anything about him, it's been the better part of a year (end of KH2), a decent chunk of which you couldn't remember his existence (imagine the guilty feeling) is from Kairi, if she tell his parents anything. The best case scenario is she just tells them he's fine.
