Maybe they're trying to frame Ruby too, Emerald putting a hallucination on her to make her see Mercury so that if she's found in a bad place and she tries to explain away that she was fighting Mercury, no one will believe her and it further discredits Team RWBY.

Begs the question as to how she might have been put under Em's hallucinations though. We don't know the range limit of it.
