She seems... interesting, to say the least...
My question is this though: is she going to be a one-shot character for this episode only, or is she going to end up being a semi-regular fixture much in the same way the Molinas and other newer characters have?
Looking at how Ladonna moved into what appears to be Arthur's neighborhood she and the Compson family will possibly end up just like the Molinas. Being used here and there in series or whenever an episode/episodes guarantees the need for them to be used again.
