Ooo, what if it ends up being Marie who trashes Walt's house? Her mental state is pretty fragile at this point, maybe Hank dies/is captured, something happens to Skylar, and Marie just snaps. I wouldn't expect that from her, so it seems like the kind of curveball we could be thrown.
You're right, that would be just be the type of curve ball they'd throw. Easy to forget about Marie.
