Eragon pg 109-115

Brom insists that instead of flying on Saphira they buy horses. At first Eragon is irritated because this will make it harder to catch the Ra'zac. Brom then states his reason and that is that Galbotrix wants him recruited our killed and the longer Eragon is away from him the stronger he can become and he will have time to ally himself with Galbotrix's enemies. With this in mind Eragon drifts off to sleep. In the morning Brom talks about dragons and how dragons are born. Dragons are born ready to hatch but wait for the right person to come by before hatching. Just when Eragon is tired of Brom he surprises him. Throwing a stick carved like a sword at Eragon he tells him to fight. Thinking it will be easy he started calmly but was surprised when he was knocked down by Brom. After regaining his senses from being knocked down he tries to leave but Brom stops him and attacks again, and once again beats Eragon. Then he tells Eragon to tell Saphira to do something and when Eragon asks why he doesnt just tell her himself he replies it is bad manners to speak to someone else's dragons. Eragon points out he did it before and Brom tells him he did what he had to.
