Well, he could be too strong to 'submit' to a dragon, but that would make him a useless Pilot and he'd eventually be TRIM'd anyway since he'd be useless to the dragon. Pilots = Dragon Tools. If the Pilot doens't act like one, he'll be replaced.
Him growing up with a dragon is impossible. Only Pilots and dragons are allowed in the Eyrie, and the dragons never submitted to riders. x3 They were a team before but that changed and a lot of the dragons changed as well, none of them for the better. The chances of a dragon accepting a new rider and respecting them as an equal is veeery low, but if you play it out right everything would be fine. ^__^
