The curious incident of the dog in the night-time 2

When i close my eyes i see Christopher alone in the train station. I can picture him being scared and feeling alone. If i were Christopher i would be scared too. I never thought he would run away by himself. I predict that he will get to his mothers house but nobody will be there. I saw a character change when Christopher went from being brave at Mrs. Shears house when he held the dog to scared being be himself trying to find his way to London to be with his mom.
