Integra sits after she does, privately a little thrown, but not so much to betray anything in her composure. She decides she'll be contacting a particular vampire after this meeting, to get more information about the orders being spoken of here. Mina seems a bit overwhelmed for any kind of interrogation.

"Don't kill anybody," she states flatly. "Don't feed on the unwilling, don't use your abilities to exploit, harm, or terrorize. Don't turn anyone. Don't bind anyone to you." It is, apparently, not a vast rulebook. "People who behave like monsters will be dealt with as monsters. That is what Hellsing does."
