Arthur, whilst waiting to get on to the train to Germany, gets the brilliant idea to take Percy with him to Germany. Percy hesitates at first, but eventually agrees to go with him.
Arthur: "I've got it! What if you come with me?"
Percy: "But I'm too old."
Arthur: "What if I sneak you on the train?"
Percy: "But that's against... that's against the rules!"
Arthur: "If we get caught, I'll just say that it was a mix-up and you can play dumb."
Percy: "Are you sure?"
Arthur: "Remember how we snuck you on the camping trip? Didn't it work out brilliantly? Just trust me."
Percy: "I trust you, Arthur. I said, I trust you, Arthur."
Arthur: "We'll go to Germany together. We'll take care of each other, no matter what happens."
