I guess it is too easy to criticize the mentally ill, but these two are the most disturbing adults I've ever seen. Ron continues to parrot his oppressive mother's martyr complex even as he prepares to bash her comatose body with a chair.
I can't wait to see Mary meddle in this one. This is going to require more than a simple, "You shouldn't fight with your brother, Ron." It may take electric shock therapy. Very cool.
