With the appearance of this maid, I can tell somethings gonna happen. The Sperado Idiots here are scheming something and it involves the maid Leslie cares about. So, there 2 things I've thought about,
Either they are already using her right now, and that "accidental" meetup with Leslie was planned to proceed with this scheme.
Or
they are gonna do something bad to her later.
Idk how this scheme that The Sperado Idiots are carrying out has something to do with burning Leslie, but it must be some sort of a way to either threaten or maybe lure Leslie.
