All Shelia's attacks are being deflected easily by the Small Knight. And now, the Small Knight no longer bothers to use his sword. He's just using his shield. And his sword is always ready to stab Shelia when she gets close.
Shelia is aware of that. That's why she would keep her distance after her attack. And she will only attack the Small Knight's right side because it is hard for the Small Knight to attack her with his left hand holding the sword.
When he has the chance though, He would thrust his sword to his right side. He can do that. But Shelia had enough time to dodge them. Though she still got herself wounded because the sword managed to scratch her.
Just a light scratch and it could damage her skin. That Small Knight is really strong.
