I'm thinking that the whole phantom Mercury attacking Yang was Mercury's semblance at work. When Yang landed the final two blows, Mercury's aura pulsated and then faded away. Notice that this isn't something that's happened at all during any previous fights.

Sticking to how there might be a reference to another work, I'm thinking that Mercury's semblance is based in illusions akin to Aizen from bleach. Instead of it being a visual trigger, he probably has to touch the opponent to have it work. The victim gets "infected" with his aura, and then it goes downhill from there. I doubt Neo would go undetected if she was the one who did it, if her semblance lets her do that kind of trickery at all.

And with how they cut to Cinder right after they were speaking about Autumn, she's totally the one that jacked half of her powers. I thought she had dust woven into her dress that let her cast that magic in the pilot episode, but it seems I was wrong.
