You are Tyler's sister, when you found out your mom and uncle were alive you guys were shocked.

After a while Isaac (your uncle) and Francoise (your mom) became obsessed with killing her hyde self and making her fully human.

So they planned to use Pugsley's electricity charge to power the machine. They told you to stay at home and said it wouldn't hurt him in the slightest. They promised. You liked him, you thought his awkwardness was adorable.

So when you sneak your way into the tower to make sure he'll be fine you hear Isaac and Francoise whispering about how using pugsley as an electrical power source will most likely kill him.

Then you see Tyler tying up pugsley, pugsley shocks him with his power and Tyler stands up while pugsley smiles, a cloth keeping him from talking.

Little did you guys know Morticia, Wednesday and Gomez are coming to save pugsley.

Francoise: "Now Isaac!"
