Why didn Qui-Gon Jinn disappear when he died like Ben Kenobi and Yoda did?
Jinn’s failure to disappear upon death is a good question, and one that Lucas says will be addressed. Lucas is cryptic on the matter, but does imply that Ben Kenobi’s statement (to Darth Vader) that, “if you strike me down, I shall become more powerful than you can possibly imagine” is very important to this. An unofficial possibility is that both Yoda and Ben Kenobi had time to meditate and prepare for death, whereas Qui-Gon died suddenly in battle.
