None of those things are actually Pyrrha. The scenario I'm imagining would involve Pyrrha 'coming back' (even if only as either a ghost, for the lack of a better term, or a voice-in-the-head).

FWIW, I can see Emerald taunting Ruby with what happened to Penny - Mercury is sure to have told her that Ruby had some connection with Penny. Jaune with Pyrrha? There would have to be some explanation for her knowing to do that.
