It was definitely good to see Professor Marchand again. He had been a familiar face back at Beaxubatons and she had missed not seeing him around when he had moved to Hogwarts. She grinned in reply and took her seat. Olivia spent the first part of the class listening to her fellow student's answers and taking notes. She glanced up when he spoke of the charm that they would be studying today. The Banishing Charm. Depulso was in the incantation. The movement was a sweep of the wand while aiming at the target. With widened eyes, she watched him gracefully demonstrate said movement. She wished that she could be that graceful with a wand herself.

A spell that would complement or counteract the banishing charm? Hmm.. She wracked her brains for the moment, trying to think of an answer. The summoning spell made sense to counteract it. But what could complement it? How about Aresto Momentum? Maybe it could be used to slow down the velocity at which the object in depulsio was hurled at? Merlin. That would look really cool if it could. "Could Arresto Momentum be used?"
