Everyone's been wondering where Ranboo's other life went. Well everyone that isn't the one who took that life away. While yes you could say that Ranboo only did ever have two lives that would spoil all of the fun. Dream finds it very fun to toy around with Ranboo and since he can use him for whatever need he wants the younger to do well...The revive book needs to be tested because he didn't know if he had copied the words right, so of course who better to use than his little puppet Ranboo! OR: Dream wants to test if he remembered all of the words from the revival book correctly so that he can make more copies.
