Fleur caught Lavender's last gaze and she to turned away, trying to hide her blush. "Oui, elle fait, ne fait pas elle?" she took a bite of her salad. Yes, she does, doesn't she?
What Gabrielle was doing didn't sneak past Fleur. She merely grinned, "Je vois que vous avez votre oeil sur quelqu'un aussi. Ne pas utiliser vos charmes si librement bien que." She warned her sister. I see you have your eye on someone too. Do not use your charms so freely though.
Soon, they were both done and Fleur excused them from the rest of the meal, saying that they were both a little tired.
Walking out, Fleur saw Lavender's gaze and met it once more and, making sure o other student would see it, gave her a coy smile before they exited the Great Hall and made their way back to FLeur's room.
