Jafar told us his wish: “Change the rule of magic”. I only new two rules. 1) Dead is dead and 2) All magics come with a price. It is like that Magic are not allowed to destroy the balance.
But what could be his motive to that. I think to that the stuff is something like the dagger or the wand of a fiary, and I love the idea with glowing eyes somethink like wishes. Maybe once Jafar got a wish ansd wanted to be a powerful sourcerer, but as we learned it in once and in Wonderland. Every wish comes also with a string, or price. Maybe the stuff who gives him the power is also something that he loved a log time ago. Maybe Jasmine, who got transformed and now he needs a reverse wish, but thats normaly also a not possibile or? You can’t take a wish back, like you can take a chess move back or somebody is dead and he wants to tries to get the Beloved back like that, cause their is no other way, cause this would break the magical rules.
So also a question is how powerful are the wishes?
