Why does Obi-Wan not mention Qui-Gon Jin in the original trilogy? After all, Qui-Gon was his master. At the end of the prequel trilogy, Yoda said that he was going to teach Obi-Wan to communicate with Qui-Qon. Unfortunately, Liam Neeson could not make an appearance in "Revenge of the Sith" as planned due to a motorcycle accident.
