paplatine knew about qui-gon?
after anakin kills mace and becomes palpatines apprentice, palpatine tells anakin that ONLY ONE has succeded in becomming immortal.
at the end of the movie, yoda tells obiwan that qui-gon has comeback from the netherworld and become immortal.
it seems obvious to me that palpatine KNOWS that qui-gon learned the secret of immortality, too. but how?
and if it was originally a dark-side power, then how did qui-gon learn it?
is it possible that qui-gon, and not palpatine, was once darth plageus' apprentice? is it possible that qui-gon is the one who thus learned the secret of using the midichlorians to create life, and thus created anakin? i know that theory is far-fetched, but i do not understand how palpatine would know about qui-gon learning the secret.
also, if any of that is true, is it possible that qui-gon was sifo-dyas?
