Harry’s Reflexes

Working from this, he tested Harry's aim, first with magic, then with a baseball, then with a repulsor glove, and finally, with a bow and arrow.

As it turned out, once his technique was corrected, Harry was a naturally very good shot. Nowhere near as good as Clint, of course, but, he had a fantastically good eye and lightning fast reflexes, like all the best seekers, and like his father, a decent natural throwing technique. All that was holding him back was his glasses – which could slip off - and his lack of upper body strength – which was about the level of a fitter than average thirteen year old.

His vision could, and after an eye exam by a couple of Asgard's best healers, would be corrected, and Clint could see both the potential for and the beginnings of a lot of wiry muscle in Harry, as well as a lot of growth. Wrenching his broom through the skies for the last couple of years had certainly not done that any harm.

All in all, Clint regarded Harry as a sort of pseudo little brother/apprentice and Harry considered him, in some respects, to be the big brother he'd never had.
