Our story of Boba Fett is ever changing, most of these changes made by Episode II.
Whoever would have thought that Boba was a clone? It was in our very loved EU, loved for reasons I do not have to mention here, that Boba oversaw the building of his ship, Slave I, by KDY. And his “brothers” are the stormtroopers of various sizes and voices. We once thought Boba in his past life was Jaster Mereel. Now it turns out Jaster was an old Mandalorian warrior, the mentor of his “father” Jango.
So as the face and what we know and think of Fett ever changes, what changes shall he bring us in Episode III? Time will tell.
