Order
Inspired by Molly, I racked my brain for Hufflepuffs that could be flying under the radar. Aida Shafiq was a few years older than me at school, and she never really stood out, but she's Pureblood and often spouts vaguely purist rubbish on the journals. If you look back at her entries, she's always quick to criticise anything that undermines the Ministry or Death Eaters (or shall we say the Death Eater Ministry?).
Could be something there, maybe not. She might just be kissing arse, but I could track her either way.
