Cool then they should have a flying elephant that shots icecream at its foes, same logic you use. Its called internal consistency, and when Qui gon gets done in by the same stab, the least you expect is a gravely injured and out of it 3rd sister. but whatever its Disney they can do whatever and you will gobble it up.
The same stab wound killed Qui gon, it should have if not killed put her out for the rest of the show. Now you are ignoring things. I didn't saw Maul should be alive, keep up. Anakin is debatable, but at least he was fucked up and relegated to a mechanic body and a suit for the rest of his life. I am sorry I like consequences for getting stabbed in the chest with a light saber more than she got healed off screen in 2 minutes, to me that is lazy as fuck writing. Enjoy it I guess.
