The last few seasons have been "plagued" by so-called do-gooders who spend most of their days reading the Bible. For the most part (with the exception of Natalie), they've kept the preaching to their bedrooms. Dan, though, has been pushing religion on the house, and this morning offended Libra by holding a Bible reading in the living room.
After the food competition, while Libra was complaining about being on slop, Dan stood outside the door with a Bible passage he wanted her to read. This just added to her whine list.
