It's too late now to run after her. Granger walks entirely too quickly for someone as senior as she is (Abercrombie could benefit from an increase in speed, for example), and her anger only fuels her lithe legs. She never complains about working late hours with him, but Draco knows it rankles her to stay past six. She tends to shift in her chair and watch the clock. Draco always asks her if she has an engagement, and, every time she grits out a long  no  , smooth satisfaction creeps through his veins. She's  his,  if only for a short time, even if Abercrombie spoils the possession with his presence.
