Ooh, she cast Protego! That was a good choice, if it was him he would not want his sight impaired at the beginning of the duel either. But wait - the spell was being deflected at him. Carl sidestepped just in time and his spell shot past his ear.
He raised his wand and was searching his mind for an appropriate spell, when Azura sent another one his way. "Protego!" He called out. A shield appeared between the two, defending him from the Knockback Jinx. It was not however, strong enough to deflect the spell.
"Tarantallegra!" Carl said afterwards, tightening his grip on his wand.
