Well, I had the same reaction when Aeris died 22 years ago. Sure, she'd taken 50 swords to the face before, but that one was special enough we weren't going to try to stop it or heal her?
Heck, for that matter I wasn't sure why Cloud would be so into someone he met, like, yesterday, as opposed to his childhood friend who clearly cared for him.
I guess Hauchefaunt was supposed to be a callback, now that I think about it...
