alternis Bellatrix Lestrange for Anton to have competitions with for "who's worse?" Also because our Narcissa needs her. Lucius Malfoy, Rodolphus Lestrange, Fenrir Greyback, Augustus Rookwood, Igor Karkaroff, Albert Runcorn, Crabbe Sr, Goyle Sr, Mulciber Sr, Nott Sr, Rosier Sr, Yaxley, and some of those future DE kids while we're at it.
And maybe Fabian and Gideon Prewett for this guy to inevitably murder.
