Oooh! Dung wants in on the Rabbit kidnapping. And Dung can also get the summons, since he already has a criminal record. It would be no surprise if he got pegged as a terrorist.
Alecto wants to help blow shit up. Yes yes yes she does! In my brain she's working on another demolition potion, and she would love to show this off!
Last but not least (I think) Essa the banshee will volunteer for the last two attacks in August (not the Lovegood attack, but Tyra knows this already).
