You are correct about the Force push. I didn't think about that because that's the Force push I always use. As is usually the case with puzzles or riddles, the correct answer is usually skipped over in favor of a more complicated one. That is the real Obi-Wan and it is the real Qui-Gon. As Obi-Wan, I simply killed Maul and took his place fighting Qui-Gon. The only trickery I used was making Obi-Wan look like it was Qui-Gon that killed him. Actually, Obi-Wan did it to himself. Shot himself in the foot, so to speak. Stupid Padawan.
