"Got to make sure none of you do something stupid."

There's rarely a dull moment in Hillingdon territory, and while Rorschach's influence of the physical world is nill, he can still take note of everything, and remember it for later. Just because he was dead didn't mean he had given up his hunting ways. When one got right down to it, it was all Rorschach really knew. He had been one of the very best, so he felt it was only right he should watch over the residents of the house, and keep them from any untimely ends.
