To a being, sitting outside of time on his couch, w a timeless beer in hand, everything in our universe, from the beginning big bang, to the end, the big sqwish, is all a done deal. He can rewind, fast forward, zoom in, zoom out. It also seems reasonable for him to be able to reach in there and make changes as long as he wants, until it's perfectly what he wants it to be. For all the inhabitants of that piece, they still react totally by their desires and decisions, from their points of view, although needing to bide by the rules of that construct. This is asuming that there is indeed a being outside of the construct, and that it is indeed a time free environment where it is, and that he has a couch and a timeless beer in hand.
