Oh my gosh, you're right, they had that week long wedding celebration with all their friends! I completely for got about that. I think they still own the land at this point. They mentioned that they will be building something quick and makeshift as soon as possible in order to fulfill the obligation that they have to start building within a certain number of years. They are bending the rules of their oh-so-loved community, by building some kind of shack to place their bus under instead of building the house they agreed to build. Again, they are disorganized and disrespectful, basically fucking their neighbors over. The reason behind building deadlines is to ensure that houses aren't isolated between vacant lots, but of course Louis and Raya are above the law, and allowed to be selfish and obnoxious.
