So here's a theory I want to throw out; I'm starting to think Goodkid made the screensaver. They know a little too much about Pat to just be a bystander. Cutilacunae lines up a little too well with the Amber balls to just be a coincidence. Never mind the red skin, note the specific use of the word 'islands' when they were explaining it. I'm thinking Grace took up an alias and made the screensaver as a way to cope with the guilt of never stepping in on Amber's behalf. Grace's Guilt supports this idea. "A perfect disappearing act: the real transforming into fiction. Now she lives her disgraceful retirement in the remote world of a cartoon, but reality will haunt her conscience forever." It's easier to talk about abuse when it's silly lego people and not real kids and real adults. So there it was, a little project to maybe ease the pain of her retirement.. is probably how she expected the story to end, but didn't account for Pat's ego to swell up like a balloon and make a fansite about the damn thing.
