Severus stopped his progress as he found a young woman standing before him. A pretty woman to be sure. But a stranger nonetheless. A quick glance over her demeanor had him checking the less than pleasant response that had been brewing. He did not have to play the detestable and strict professor here. Though Severus wasn't yet sure what stance to take quite yet.

"I can assure you, miss, I did not expect to be here." Severus then gave a slight bow. "I will not linger and leave you to your solitude if that is your wish." He was reminded not of Narcissa, but more of Narcissa's older sister, Andromeda, by this lady. Something about her struck him to be a person more along the lines of the disowned Black daughter. Would this association within his mind last? He would have to wait and see and adjust his reactions accordingly.
