Hobbes reminds Calvin the last time he made a duplicate of himself, the duplicates made duplicates. It was a mess. Calvin agrees, but he says with the ethicator, it can't happen this time. By only duplicating his good side, he's ensured this duplicate won't cause any trouble. He tells Hobbes there's nothing this duplicate likes better than making everyone's life easier. He lives for it. Hobbes thinks the ethicator must've done some deep digging to unearth him.
