Jeremy was in at least as bad a mood as Owen soz everyone, and was probably a little more brazenly 'let's fuck some shit up' than he might have been usually or with this group of people before.
He brought up that he thinks they need to make things harder for the ministry to function and make things harder for the death eaters, since they pretty much have free reign and they aren't afraid to do whatever for kicks. He isn't necessarily sure what that looks like! But it could probably include nuisance things like bees in the ministry or things in that vein but also possibly things more serious!
He also brought up wanting to talk about what they could DO about the Death Eaters, especially the ones whose identity is known and who are off casually intimidating and killing people on whims. What can they do to help stop these DEs from killing people?
