Here's a perfect example of why I adore hp_beholder: because it lets me say, in all seriousness, things like, "I loved the one about Dennis Creevey's threesome." You've brought these characters alive in all their fat, scarred, scrawny fabulousness. A few of the many parts I loved:
--Dennis had the vigour and clumsy enthusiasm of a newborn centaur foal, all gangly limbs and an impressive startle reflex.
--(although he suspected that Snape might have made things out to be more complicated than they actually were, especially the part about the Reverse Starfish).
--the superb question-and-answer paragraph
--the effective use you make of Colin and the camera and just your overall ability to mix hilarity and poignance and pain and humanity.
