I really hope that this is just the first match of the singles round, because that means(presumably) that Pyrrha would fight Penny. If Pyrrha really is Ozpin's guardian, then Pyrrha vs. Penny could be seen as Ozpin vs. Ironwood. If Pyrrha wins it shows that Ozpin's way is better than Ironwood's.

Then, assuming that Mercury beats Yang, since he's basically her weakness, the final signals round would be Pyrrha vs. Mercury. If Mercury wins it shows that the villains are a force to be reckoned with, and that not even Ozpin's method will work for protecting the world.

All of which effectively shows the show getting dark, and that this war won't be as easy to win as our heroes think it will be.
