Now that I think about it, her fighting Mercury would also make sense. Someone up higher said that, but the more I think about it, the more likely it seems. They catch on to what purpose Emerald and Mercury serve and Team RWBY decides to try and take them in. Plus, if you think the opening to Volume 2 is a scene of what's to come, then it would make sense for Yang to fight Mercury at some point in this Volume.
