Yeah, this would probably be how it would work out… until and unless Fluttershy heard about Elmira doing this sort of thing to an animal. Then The Stare would come out, and I don’t think Elmira is genuinely evil(more oblivious)/strong willed, and definitely not magical to tank it like Discord did (whichever combination of those explanations one prefers for how he did that).
Would be like Pinkie x Deadpool.
