Nellie falls off of Bunny and pretends to be paralyzed. Mrs. Oleson blames Laura for this and wants to destroy Bunny.
I don't know how I missed this when it came out. Perhaps it was not shown in the UK. However, three episodes in, and I am hooked. Good plots, dealing with situations that are still relevant today, and will probably be relevant a good way into the future. If you love Fringe, or are a science/conspiracy fan I would suggest you watch this :)
Great show, wish it was still around and the ending was fantastic
