My Prediction of Chapter 6

I think when Rob comes home and gives the letter to his dad he calls the principal and says Rob's legs are never going to clear. But the principal says just give them some time. While he is at home he goes to see the tiger and one day he goes to the tiger and it's gone. And then he can't stop thinking of it. So then he hears some roars and he follows them and he finds him self right next to the tiger.
