I have doubts if Lite is the reincarnation of Fire or Feather.
In my opinion Fire has Lite's personality, but I remember Kyoga cursed Lite and look at these horrible things that happened to Feather:
1) Proudmane kill his father and his sisters.
2) If he stayed in the pride, Proudmane would kill him.
3) If Nothing didn't save him from a huge tree branch that almost falls on him, he would be dead.
4) During their journey through the Prideless Stretch, Nothing and Feather lost Fire's trail. And they suffer from hunger and thirst.
5) Because of hunger, Nothing almost attacked him to eat that ostrich chick.
6) He wouldn't be able to survive through the Prideless Stretch alone, if Nothing would choose to decide to abandoned him and join Rain (Cansu).
7) He was almost killed by Fire, and because of that he has a neck wound. And it is not known if he will be able to walk normally or not, because for him to try to keep up with Nothing and Ghost, he ran with a limp.
8) Now he is alone in the Prideless Stretch.
