The meeting of Dumbledore's Army had ended over an hour ago, but one person still remained in the meeting room, Neville Longbottom. They had been working on repelling dementor's today with the patronus charm. Neville had been unable to perform the charm all through the lesson and any other day they had practiced. He was the only one who could not do it.
"Expecto Patronum" he said. Nothing happened.
"EXPECTO PATRONUM!" screaming didn't do anything either.
Neville remembered what Harry had said about thinking of the happiest memory you could possibly have. His original memory had been the day he had found out he was a wizard, he was so happy not to be a squib but now Neville realized that wasn't entirely happiness, it was more of just relief.
Another memory then appeared in his mind. It was a week before his parents went crazy. His mother and father had taken him out to a picnic in the country side, a place where he used to visit all the time and that was not touched by the imposing war intruding around it. That day he'd eaten his mother's homemade strawberry jam and had flew kites with his father and magically made his toy dog run around as though it were real. At the end of the day he sat with his parents in the flower filled field and watched the sun set.
Neville filled his head with the memory of that day and let it remind him of his parents, memories he usually pushed away.
"Expecto Patronum" he practically whispered.
A thin sliver of blue-silver light burst out of his wand and began to grow and create a shape.
Neville admired his patronus as it stalked around the room, all the while the memory of his parents in his mind. Neville stayed there long after the patronus faded away, soaking up the happiness that it and the memory had brought him.
For the next week the image of the patronus stayed etched into Neville's brain. The patronus had taken the form of a lion.
