- the minor interaction with surroundings we see in ROTJ don’t matter near as much as finding out that force ghost Obiwan and Yoda maybe could have appeared before the Emperor and Vader and zapped them.
But Yoda didn’t just zap the tree out of thin air like the force lighting the Emperor uses. This has already been explained to you.
Whatever you want to call it, it sure would have been nice if had used it on the Emperor in ROTJ after Yoda died.
Please point me to the scene in the Emperors throne room where there were storm clouds over head so we could have had the same lightning and then i’d agree with you.
