When Harry got back to Gryffindor Tower, the news was as bad as it could possibly be. We'd been grassed on by that bloody, bloody Marietta Edgecombe, who'd been dragged along to the DA by Harry's current lust-interest, Cho Chang, the Ravenclaw Seeker. Edgecombe's mum worked for the Ministry, and she'd been uncomfortable with the whole idea of the DA from the word go. Luckily, my jinx on the parchment she'd signed kicked in, and she was too upset to talk---vain little thing!---but the words "Dumbledore's Army" at the top of the parchment were as good as a signed confession from Dumbledore himself.
