Grace didn't expected her spell to hit anyway, but a small hope... Lyra was too quick. With casting spells too! She didn't know what 'Rictusempra' was, nor did she care. All she knew was she had run away. Fast! Trying to remember the blocking spell, she threw herself to the right while shouting "Densaugeo!" Another tricky spell she had learnt from his dad's diaries which caused the opponent's teeth grow very fast.
