Alexis had no choice but to bear the full force of Sean's roundhouse kick, which sent her sliding to the wall and hitting it with enough force to cause a boom upon contact. However, Sean had kicked straight into the sharp side of her arm blade because she had lifted both arms to brace for the impact of Sean's attack and diverted the force of the kick from her head and onto her entire body instead. Alexis was too busy recovering to assess the damage the arm blade did, but she could definitely pick up the iron scent of blood in the room. Still, regardless of what happened to Sean, she didn't waste time and, once she was engaged in melee with the elemental master, retaliated with a roundhouse kick on her own with a lot of force behind it. It was as if Vincent's assistance had, through some logic or reasoning she had yet to understand, moralized her and provoked her at the same time.
