"I'm sorry that I had to put myself in danger and that it upset you, but I'm not going to be sorry for saving my dad's life. Not just him--Scott's mom and Allison's dad too. Where would we be without them?"

Scott would have had to go live with his douchebag dad and he and Allison would have been orphans.
