I think this is the episode where the gang finally defeats Hades. (Keep in mind that Defeat can mean many things). And also escape the underworld. basically, it's the end of the UW arc. The next episode (Last Rites) will be the bridge episode between the UW arc and the Finale (just like Lily and Mother formed a bridge between the QoD arc and the season 4 Finale).

I will agree that the Emma Flashback and Cleo are still not making sense right now, but hopefully all will be explained when we see what the writers have crafted.
