Thank you so much for organizing this and all the work you put in to making this an awesome fest.
Someday soon I hope to have enough time to read through all the stories I haven't gotten to yet.
Filius, Myrtle and Walburga, hunh?
I wonder how they would fit together? When did Myrtle die? Is there any chance she and Walburga might have overlapped at Hogwarts? Might Filius have been there at the time too? Myrtle and Filius were both Ravenclaws and I'm guessing that Walburga was in Slytherin.
*** *runs off to check lexicon* ***
Walburga Black is listed as being born in 1925. It is likely she would have entered Hogwarts in 1936 and graduated in 1943.
Myrtle died in 1943. The lexicon doesn't list what year she was in at the time. I'm guessing maybe 5th.
There are no years listed for Flitwick's birth or attendance at Hogwarts. All we know is that he is "ancient" and that he has been teaching at Hogwarts since the 70's. It could be reasonably argued that his years at school could have overlapped with Walburga Black and Moaning Myrtle.
If one supposes that Walburga might have been inclined to mistreat those she saw as her inferiors (read, anyone not of the highest pure blood standing) and was likely as sadistic as others in her house (Tom Riddle was a year or two behind her) I could see her tormenting a younger student of another house, especially one so prone to victimization as Myrtle.
Perhaps Walburga Black is a prefect for Slytherin and develops a sadistic, dominating relationship with the vulnerable Myrtle, forcing her to sexually service the inner core of Slytherins. Filius, as a prefect for Ravenclaw, notices that something is wrong with Myrtle and tries to get her to open up to him about what is happening. She has been trained well by Walburga and knows that her mistress will punish her if she tells so she attempts to distract Filius from his questions by seducing him. Poor Filius is a virgin and even though he knows it is wrong, he cannot bring himself to stop the blowjob Myrtle all but forces on him. Afterwards, he is deeply shamed but seeks out the advice of the Head Girl, Minerva McGonagall because she is easier to talk to than the Head Boy, a Slytherin who is scornful and taunting (and in on the whole sex slave thing, even though Filius doesn't know that). Minerva agrees that they need to do something to help the troubled girl and they go looking for her. It takes a few hours to discover that Olive Hornby was the last person to see Myrtle. By the time they find her in the girls toilet, she is cold and dead. Myrtle's connection with Walburga and the other Slytherins is never brought to light.
