Even taken inconsistency into consideration though, the fact we see Yang walking straight away from Mercury before the semblance sound is weird given we see her walk beside him on the cameras.

Only thing I can figure is she didn't just hallucinate him attacking, it was a full on sensory highjacking, and what she experienced as him attacking, was her walking in a circle around him before attacking. Not just a visual high jack but her balance, sense of motion, sense of touch, everything.

Which is kinda way over the top for a semblance in this show.
