"Are you saying that Miss Granger walked into your room the night before yesterday to report the Ministry of Magic's financial report to you?"

"Yes."

"Are you saying that Miss Lovegood walked into your room last night because you found the harassment fly?"

"Are you saying that Miss Qiu Zhang will come to your room to practice Quidditch later?"

"That's right."

"Are you saying Clearwater, Bones, Greengrass, Delacour, Nymphadora..."

"Please allow me to interrupt you. I will clarify here for the last time that these... are not rumors."
