They alter memories. I remember on the first all-star that Lex's mouth dropped open when Kathy kept her immunity necklace for herself. He denied that being his reaction, but later he admitted that maybe it was. He just didn't remember. To me, real life is more interesting than a scripted plot thought up later, but the majority don't seem to mind.
