Jack's mother had not taken her child to the hospital to have his wound dressed right away in order to please Pete.
For so many years, their family had been trying their best to turn Jack into Pete's right-hand man. Unfortunately, both Pete and Justin were very indifferent to others.
This was especially true since Pete also had mild autism, which led to him not having anyone close at home.
That was why Jack's mother saw this incident as an opportunity, despite his injury.
She said, "Yeah, Pete, tell him what happened. Quick, tell your dad just how annoying that boy is. He often loses his temper and bullies others for no reason. He's too domineering. He's also very savage and has no manners whatsoever. Get your father to kick him out of the house, or take him out and have him educated before he moves back in! Otherwise, with so many children in the house, who knows who would be bitten next?"
