Fleur looked to the older man with her signature arched brow as he seemed to struggle with what to say. She was used to men losing their words around her and she knew they usually found them after a few moments of waiting. Well, as long as they weren't hormonal boys. Or a certain young Weasley brother whom seemed incapable of ever growing out of that stage.
When Slughorn stopped again and spoke, Fleur felt a knot in her stomach. She knew that that had been a high possibility. She had seen the familiar glint in Carrow's eyes. That only made her worry more. If Horace, a man not familiar with looking out for such things could notice the hidden intentions than they were certainly there. This only made her worry worse.
Fleur could vaguely hear her lovers laugh and hoped that Slughorn hadn't. "Again, Professeur, zhank you for letting me know. We...we need to stick togezher." She said lowly. She meant the few teachers that did not stand with the death eaters. But she knew she shouldn't say that out loud. It was too risky.
