Narcissa informed Hermione that the Hogwarts aged children of Voldemort's followers knew she was his guest and they should behave accordingly. She also mentioned that with the Dark Lord in residence many would be in and out of the unofficial headquarters. Also, Draco's friends tended to flock there over the summer.  Draco either ignored her existence or sneered silently. Marcus's friends found her witty and delightful. Pucey and Warrington flirted with her shamelessly and generally enjoyed the sass they got back. Boles and Montague enjoyed picking her brain and riling her up with intellectual debates. When asked by schoolmates why she didn't try to boss them about she rolled her eyes. "I don't care enough. Why waste my breath?" She continued to impress the older generation and an unease truce seemed to have been reached, well, almost.
