The big bad Queen of Darkness Victorious made her first appearance since the first episode. But actually, she'd been in the show almost the entire time!
Maple drank whiskey with Dagger after he got booted from his evil plan. I don't see how Dagger can drink whiskey in the form he's got right now, but he needed it anyway.
If the Big Bad shows up near the end of the season, that must mean the Great Good needs to make his entrance too. Oh, make that Grateful King back from retirement. He's still got the hair, obviously.
