The Khadgar we got from Xal'atath isn't real

She's a powerful old god that fakes forms to manipulate in like every single cinematic. We're suppose to believe she just spat out Khadgar? I'm thinking her illusion of a Khadgar-on-the-brink-of-death pushing Anduin to wield the light again is going to be some huge part of her plan.

Also, I'm not sure why he still has both hands when one of them was clearly obliterated.

Edit: saw this quote from N'zoth, is it relevant? "When the arrow finds it's mark, the last fetter will fall away."
