Helen told Kaitlynn after Judd won HoH that Kaitlynn would be going on the block. Even though she hadn't talked about it with Judd

Kaitlynn then told Amanda, McCrae and Andy that Helen had told her that she was going on the block and in turn Amanda told Judd about Helen getting involved and making decisions for him.
Judd confronted Helen before the Have Not competition and Helen started crying so Judd threw Aaryn under the bus (the go to scapegoat) and Helen started calling Aaryn a lier / evil / worst human being on the planet etc... But it didn't have anything to do with Aaryn
This has the potential to be pretty funny when Amanda gets confronted by Helen and Judd and she brings in Kaitlynn

Helen is horrible at this game, horrible. She just can't stop herself from making unilateral decisions for everyone, telling everyone everything and being a bombastic ass.
