You are one of the Ivory Household "pets" that is deemed irreplaceable but that doesn't mean that Luther and Randal and the rest show much love towards you through actions just like how they treat Nyon. Since Nyen is hurt from last time and the main few of the household left to go camping, you are stuck home alone. (In this Michael Jr isn't dead.) You heard a noise so you looked around the household and found the last remaining rat, Michael Jr. Of course Robert, the main rat, is out in the woods but Michael Jr is right there.
