Pax by Sara Pennypacker is a book were we have learned about some characters such as Pax, Peter, Dad, Grandpa, Bristle, and Runt. I split them into 3 groups. The starters (Pax, Peter, and Dad), The Peter side (Grandpa) and the Pax side (Bristle and Runt) I think that later in the book Peter and Pax will get sidetracked off their mission to find each other and get caught up in other things. On the peter side I think that Peter will ether get caught by the police or his grandfather. On the Pax side I think he will start living with Bristle and Runt. I also wonder what Pax and Peter will do if they find each other.
