A/N: Our next installment in this little series!

Snape's foot beat an irritated tattoo on the floor, a dark scowl painting his face. The insufferable witch was late, of all things!
For weeks, months even, she had been wheedling at him for private lessons, apparently nine NEWTs and a Mastery in Potions hadn't been enough for the little Gryffindor know-it-all.
Not that he could claim surprise at the fact, the witch may have matured nicely in her years since the war but her insatiable need for knowledge had remained the same, something he had personally witnessed as he simply couldn't seem to get rid of the witch.
What had begun as the girl's entirely unwanted, incessant presence at his hospital bedside had morphed, quite without his permission, he would add to anyone who asked, into a strange friendship of sorts. At least he supposed that was what one would call it, a mutual tolerance might be more accurate. His tolerance wasn't going to last much longer though if the witch didn't put in an appearance soon. He hadn't dragged his arse out of his warm bed before the sun just to while away his morning in the as yet stone-cold Room of Requirement. Damned room had never liked him.
He glared for a long moment at the door as if he could will the bushy-haired woman to appear, but the portal remained firmly closed. With a frustrated growl, Snape drew his wand. He was simply going to have to summon the tardy witch, he certainly wasn't going to allow her to enjoy a Saturday lie-in when his had been ruined.
"Expecto Patronum."
Without a thought, he cast the spell that had come so easily to him since the war, sending silver light streaming from his wand. What happened next, however, was most certainly going to ruin his day.
