Not realy Zolnir, what o did here is a sum of my late theories linked to facts, now known as "common known". I wont start chattering about things i dont know, or that will hapend in the future, my theories are based on what i have in these few 6 shot episodes :)

About the last assumption,  i said its my bet, i dont have info to assure White Aura/Dust has healing properties, but its my feeling about one of  White possible properties. I wont assume my theries are the truth of RWBYverse, thats why its called Theory

And Pyrrha could had mean by "why he didnt use his Aura" as he could strengther his body to avoid minor damages ... its all about possibilities :)
