i believe larry is xehanort because if you have watched that scene in kh2 fm xehanort is talking to aqua's armor and reefers to it as a friend if im not mistaken
im pretty sure the 3 knights are a family
-first reason: theres a man, a woman, and a boy; man + woman=boy
-second reason: the man holds back the boy to protect him like a father would
-third reason: you can see how sad the woman looks when the boy is frozen
It is my belief is that the key blade choses people who want to protect somoeone or something and everyone else get one on their own. my reason for believing this is...
Sora: has the biggest heart and wants to protect his friends
Roxas: nobody of sora
Riku: wants to later on in kh2 protect his friends (when he gets it in that scene in kh1 at hollow bastion i think is because at that moment he had the stronger heart than sora)
Kairi: got it from riku who probably got it from the dark realm and she also wants to protect her friends
The Bald guy: toke it probably from the realm of darkness
The guy with the Bald guy: not sure
The 3 Knights: they want to protect each other and i think they are a family (because man + woman=boy when the man approaches he holds the boy back like to protect him and when he gets frozen the woman looks extremely sad)
King Mickey: he got his from realm of darkness
...and i also believe that the keyblade chooses people who protect their friends because in the scene where roxas and sora are fighting roxas is in the air and is looking at sora on the ground and on the floor around sora is images of his friends and roxas realizes why the keyblade chose sora
