Indeed, your sketch has intrigued me. I love to hear more about the unexplained arcane devices with which JKR has casually endowed her characters. You have brought the clocks to a kind of startling life and usefulness in the Headmaster's hidden chamber, and your analysis of Severus Snape's relationship with his two Masters is equally thought-provoking.
Snippets that gave the piece real life for me:
--the shape of the room and its meager contents--except for the clocks, of course,
--the differences among the clocks,
--the untouched lemon drops and their reason for being there,
--the word perii on the trunk,
Thanks for a delightful read!
