Reggie's attack hadn't entirely succeeded, but he continued to press his attack. He knew retaliation was coming, and it was coming hard, but he wasn't gonna retreat. It would only put him at a disadvantage due to his weapon's length. Instead, the boy went low.
Reggie figured the boy was going for a stab when he changed his grasp on the weapon. He had little time to react, so he went for what he thought was reasonable - he ducked low, letting the blade graze his back, while going for a hard stab at his foe's gut, wielding the dagger with both hands. He put a lot more force into this attack than he had with his previous ones, meanwhile activating his semblance so that his opponent's weapon would likely be pushed upwards by a flow of air. Not enough to disarm him, but at least it was something.
