I feel like a Eustace who had been brought up in Narnia would be more mellow than usual, and if he had been brought up surrounded by an entire court who can ground him, would get into this whole liking/admiring people thing a bit earlier than he does in canon. But still, can’t take the Eustace (and the science!) out of the Eustace. :D
