Dear RJ, Zane's power source… is Chi. (from Chima) Case closed! :)
Why did everyone act like Jay was the only one who could make the final wish to
defeat Nadakhan, when there were tons of people in Ninjago with unused
wishes?-ShinyShiny9
Because Jay was the only person who could get close enough to Nadakhan so that he
would hear his wish. Djinjago was difficult to get into, even for a highly trained ninja. It
would be improbable for an ordinary person to get there. Even if the ninja tried to help
them reach Nadakhan, they would hamper the mission so badly, they probably wouldn't
make it.
