If this had been a few months ago, suggesting "Let's spend the night in the captain's room" would likely have met with disagreement.
But if it were said, "The house isn't finished yet, we can only sleep together with the captain," everyone would think it's only temporary for a few days, and would reluctantly agree.
Now, saying "We need to supervise others to make sure they don't do anything bad with the captain," everyone would think since they all had shared a room before, sleeping in the captain's room now seemed like an acceptable idea.
In essence, that's how boundaries get pushed, step by step. It will eventually evolve into "It's fine as long as no child is conceived," hmm~
