Like, maybe Qrow comments that Yang's Aura shouldn't have regenerated so quickly, and Blake points out that her Aura actually didn't hit 0, and something Adam did was able to ignore her Aura or whatever thing that Adam did. My theory: Adam's Semblance. We got to watch the Seeing Red background again. Adam disintegrated the Spider Droid with one clean cut that also cut through the cargo and the forest behind. He also told Blake to move suggesting that his attack is so powerful it could also kill Blake if she had been hit by it.

I believe Adam's Semblance allows him to cut through anything and everything, including Aura.
