Cass watched, for a moment worried that Montague would actually attack him (he really hadn't thought so far as to ask for any security for this meeting). Then he seemed to - at least physically - calm himself, though it was with a rage that Cass had never heard before that he responded.
'Me???' Cass exclaimed, not completely without anger himself. 'I'm not the one who joined the Death Eaters, I'm not even the one who went looking for the news that you had!' he exclaimed.
'I never wanted you to be a Death Eater, I'd give quite a bit for not knowing what I know. If you want to be angry at anyone be angry at yourself for joinging - or if you can't be - at Miles for telling me in the first place!'
'I never wanted to know and I've been bloody fucking brilliant at keeping my eyes off the lot of you during this years. What the fuck was I supposed to do when Percy asked me outright if anyone else of my friend were Death Eaters? Lying wasn't an option and I don't think he'd appreciated the answer "I promised Miles to keep my mouth shut"!'
