So from the canon point John's from, he's pretty much immortal and earned the ability to control wind, which allows him to alter to currents to make him and other things fly, making tornadoes, etc. He didn't really learn the abilities, they came naturally to him once he got them. Would those still work and would he still be semi-immortal?

And would he still have his sylladex (an inventory system that can hold a loooot of stuff) and the items within it upon arrival, or would all those items be gone when he arrives and only re-obtainable through item requests?
