Oh! OOOOHHHHHH!!!! This is glorious, wonderful, and all sorts of fantastic! The essence of this fest – four underappreciated minor characters, unembellished in appearance or character (which is exactly what makes them fascinating), well-written and thrown together in an inventive plot that could well be (and in my case, now is) canon. I could quote virtually the whole thing back at you, but I'll restrain myself to these lines:
Normally Dolores took quite a lot of sugar and a dash of milk as well, but for some reason she did not want to insult the British palate in front of this woman. -- Example 1 of x of what I love about your portrayal of their interaction. Just the right amount of tongue-in-cheek, hilarious but never overdone.
"Nice doggie," she said experimentally. Ripper passed gas. -- *dies of laughter and ABC poisoning*
"I’m all woman, mind, but I’m no shrinking violet." ... "And what about you, if may be so bold? Is there a Mr. Umbridge at home? Surely an accomplished woman with a fine figure like yours must have to beat them off with a stick." Marjorie asked, her face a touch flushed from the large swallow of brandy she had just taken. -- Love Marjorie's flirting abilities. And I love how you show both of them with all their flaws yet keep them on the human side.
Ripper here has taken quite a shine to you." Ripper licked his privates. -- *dies again*
Leave off that nonsense with the professor’s leg this instant! -- *resurrects (nice day for it after all) only to die once more*
I also love the Millicent/Myrtle plot, and the way you tie it together with the Dolores one in the end.
