In the end, Ryan gave some pointers to the Colonel and his men. Although he was giving for free the information, that was basically the secret of the best method he could use to hunt the monsters. He didn't feel bad or worried. Ryan intended to use only long-ranged attacks against a large number of enemies and while his other fighting style was being developed. Besides, he had other secrets that were more useful, and other people weren't aware of it. So, it was fine.
As for Alissa, no one could learn much by watching her. She was impatient, and since she relied too much on her draconic powers, one could easily notice that she lacked discipline and technique. For others, it may look like she was wasting her draconic powers, but for Ryan, who knew the life she had before the monsters' arrival, it was only natural that she would be like that.
