The maid is the the clown from the wagon that Allen hitched a ride on last chapter.
And is the Millennium Earl serious when he gets angry about "being disturbed" since Leo kept talking about him? I mean, the Earl does this stuff for fun, right? and he gets to watch what Allen is doing.
Idk if the Earl is an unreliable character or not. I'm not sure if anything he says is to be taken at face value.
