Rolf's lips twitched. He sincerely doubted that almost anyone realized his grandmother had been a Slytherin, anymore at least. After all, she was so very old now; it was beyond many's reckoning. But the woman had raised him probably more than his own mother, and despite her many faults, she had tried with him. And these days she was much mellower, in as far as one could ever call Porpentina Scamander mellow.
Dear Miss Bulstrode,
Perhaps it was slightly improper, but there was no way I was going to leave them on your doorstep, inside-larger and temperature controlled carrier or not. Besides, every work place could do with a mascot or two; Meep and Neep seemed quite at home (and several of your coworkers seem to approve).
However, motivations are such slippery things. Are you quite sure you have me pegged? This little Hufflepuff simply wants his furry friends to be in a loving situation.
Sincerely,
Rolf Scamander
And okay, perhaps he was having a bit of fun winding her up a bit; it was just so easy today. And he hadn't seen his sisters in weeks, with them being on vacation.
