This is the part where we are edging onto what I cant talk about I will say though it didnt involve pyrrha.
But some stuff on par with pyrrha or Ozpin saying Silver eyes can be used or cut depending on if they think it will work better or not.
Its not them removing or adding things for no reason though its ALWAYS aimed at making things better for the show either flow or just the context of what is going on.
So if its in the show its because they think its only going to help them tell the story they want to tell.
Its not throw away filler.
