They fixed Isaiah

With the Titler, although it wasn't the Amulet of Exchange, they didn't realise that was what they needed, so they simply used the Titler after reading the user's manual in the interface to turn Isaiah back into the "original Isaiah before the body swap", saving Isaiah from his life as a mutt, causing Isaiah to start beating on Dilly. However, the girls stopped him as they separated the two, deciding what the fate of Dilly should be.
