My brothers friend

I'm Tim Shepard's little sister: Bella. Along with my little brother Curly and my little sister Angela. And for some reason Tim is best friends yet also enemies with this kid Dallas Winston. I always see him at Buck Merrill's parties or just in general, over at Bucks. Buck is a friend of mine even though he's much older he knows not to cross the line, plus he's got some damn good stories so he's a good friends. One day, I find Dallas sleeping on my couch in the morning with two other kids that I had never seen before. What happens when he wakes up angry?
