Completely forgot to note here that I have actually written something again.
It's called Do Pass Go, was written for
HP Beholder 2013 and the definitive version is here on AO3:
http://archiveofourown.org/works/817947.
It features Millicent Bulstrode/Dudley Dursley and is the longest fanfic I've written to date with ~5000 words.
Enjoy. Maybe
