If Brett and Bate had their rooms reversed, would their dynamic have shifted? Or would the rooms have catered to them differently?

I think the results would have been fairly similar. I think the room that would have shook things up the most would have been the nursery–in that case, what I was planning, was that whoever was the “little brother” at the moment would have to become the baby of the house, but alas, the paths unexplored, right?
