If we're talking about sheer nonsense, how about the incredibly over-complicated plot to get Ali out of the house?

No no, this requires creepy phone calls and old-timey music, and also masks and mannequins and hoodies, because why not! we're going full red herring here, so let's just throw literally every single A trope at the thing. It was just too much of a "HA, gotcha!" to the audience, and I definitely would have taken 3 more minutes of Mona singing to herself in the Hole over watching Rosewood PD fail at its job some more, again.
