If you'd asked me what I'd most like to see as the opening hp_beholder entry, this would be it: Severus. Minerva. A Victorian conversation chair (*dies of furniture love*). Stylized black-and-white with a perfect note of red. Revealing, IC expressions. Exquisite shoes (and sleeves and fichu).
I like how believably weary they both are, and yet there's closeness despite the separation enforced by their circumstances (so nicely symbolized by the chair arm).
