In sum: it's a nasty room that Hildi pulled out of a particularly tasteless part of her ass. She gets points for no structural damage, but that's it. There was no good reason for that yellow; it was just hostile, pure and simple. There are some occasions when you can make a case that Hildi has a shred of design sense -- though this episode won't be high on the list of those cited on that front -- but even her apologists are hard pressed to make a case that she consistently exhibits any common sense.
