Relic of the Future: Chapter 9, Chapter 10 Author's Note

Jaune slumped and caught his arm, his left – right on the forearm. There was a red line there where Tyrian's stinger had drawn blood. He could already feel it burning.

"You'll pay, oh yes, you'll pay," Tyrian laughed. "For daring to speak ill of the Queen – my Goddess – you'll suffer the most unimaginable agony." His smile grew. "You know it, though, don't you? Yes, I can see it in your eyes. You know who I am, what I am, what I can do. You know you're already dead!" He cackled.

He knew about the poison, yes. Even as Tyrian said it, Jaune's vision swam. It felt like liquid fire in his blood and he finally understood what Qrow must have been going through. Unlike Qrow, however, he had a trick in store and flooded his body with aura, activating his Semblance at the same time. The burning receded, though it didn't fade entirely. His muscles spasmed and his eyes watered, making it harder and harder to keep track of his foe.

On aura and Jaune being wounded last chapter, though I didn't explicitly say it in the text I meant it in the way that due to the darkness in the room, the crazy melee and the surprise, Tyrian was able to bypass Jaune's aura – as Ozpin said happened with Oscar because aura has to be controlled and focused, and isn't a passive defence. The basic idea was that Tyrian surprised Jaune specifically because Jaune was lost in thought trying to figure out how Tyrian fit into this and future knowledge, etc… I.e. Jaune was stuck in his head and not paying attention to the fight.

I know it's confusing because Rooster Teeth basically stated in a WoR that aura is a "Passive Defence that works like a force field", but they ret-conned that in V5 by having Ozpin contradict it and explain that aura can only block attacks it sees coming, and that the wielder has to focus on it. It was Jaune's focus that wavered in the fight against Tyrian last chapter, specifically because he got lost in his thoughts and stopped paying attention.
