I for one think Emerald and Mercury are hallucinations.

Think about it. They left the Academy on this airship thing, with one of the characters saying they were leaving to see Mercury's "Family", why would they all of a sudden return, plus wouldn't any of the audience notice Emerald, plus there's no way Ruby could see Emerald across the entire arena, she'd need like Eagle vision to be able to do such a thing. That and Cinder told Mercury to lay low, so he's all of a sudden walking around. That's why I think Ruby might just be hallucinating. There's no way they could've also returned so fast.....I think this is Cinder's doing, she hasn't shown her full potential and seeing how mysterious of a person she is, having a variety of powers and abilities. I wouldn't be surprised if like Emerald, she can cause hallucinations as well but far better than Emerald thus why she's able to do it out of sight where Ruby doesn't see her.
