Okay, so Christopher's standing in the train station, and he's totally overwhelmed, just as he predicted.
He's dizzy and nauseous, and feels like he's standing on the edge of a cliff. He's having a really hard time thinking straight with all this, and he just wants to go home.
He finds a table in a corner, closes his eyes, and tries to do some math problems to calm down. (That's Shmoop's favorite calming trick, too…)
When he opens his eyes again, there's a policeman standing above him. It turns out Christopher has been sitting there for two and a half hours now. Time flies when you're doing math.
Christopher wonders if he should tell the policeman about his father killing Wellington.
Instead, he tells him that he's going to see his mother in London, but doesn't know how to get there.
The policeman helps him use his father's bank card to get some money – thank goodness for the help. Christopher doesn't even know that "quid" is slang for "pounds," (kind of like "buck" and "dollar").
Christopher leaves the policeman and goes to buy his train ticket. But it turns out that isn't so easy either.
The man behind the window tells him where to go to catch his train. Christopher is still feeling terribly uneasy, so he imagines a red line along the floor that he can follow to the train, and says "left, right, left, right" quietly to himself, to try and calm down (191.104).
A couple of people bump into him on his way to the train and he barks at them like a dog.
Finally, he finds the train, gets on it, and, well, he's on his way to London.
