The exclamation didn’t include her name but it was close enough that it pulled her attention none the less.  Finding the speaker it became obvious that the exclamation was indeed for her.  It took her a moment to piece together who he was… after all she'd only known him in a place and time she thought she'd completely put behind her. 

"Signore Zabini?" she asked, so utterly surprised it was worth confirming it was actually him.  "What are you doing in Hogsmeade?" With a baffled smile she'd turned to step closer to her old acquaintance before realizing she'd abandoned her manners and nearly abandoned Mr. Carmichael. 

"Forgive me," she said, flashing an apologetic glance to Mr. Carmichael.  Instead of moving towards him, she beckoned the newcomer to join them.  "Mr. Carmichael, this is Sig. Zabini.  I met him while studying in Italy.  Sig. Zabini - this is Mr. Elliot Carmichael.  He was my Divination Professor" It was not the most graceful of introductions but it was fortuitous.  In her limited interactions with Sig. Zabini she'd always thought he and Mr. Carmichael ought to meet. 

To Sig. Zabini she added "You may recall me mentioning having differing experiences in Divination with someone…" Instead of finishing her the thought, she simply waved a hand towards Mr. Carmichael with a wry grin.
