Diesel gives Paxton a terrible fright when he makes him think that all the other diesels have disappeared. He hides and races away from Paxton. But when Diesel runs out of fuel, it is Paxton who takes him by surprise by offering him help. Paxton gives him a push to the fuel tank, and a taste of what friendship might be like.
