Cilla moved a bit so that she had a good amount of working space surrounding her. She aimed her wand at a spot a few inches in front of her and focused on her happy memory. She moved in wand in a circular motion and said firmly and clearly, "Expecto Patronum." Nothing happened.

She wasn't going to let it phase her considering Professor Dakest said for the students to not be worried if they didn't produced a patronus. She really concentrated hard and repeated the wand movement and incantation but a bit louder.

"Expecto Patronum!"

A trail of wispy smoke emitted from Cilla's wand and floated in front of her. "Not bad," Cilla thought to herself but she wanted to conjure a corporeal patronus.
