Hello and welcome! I'm Anna with just two here (for now).
First of all, this is Alecto, Death Eater and pyromaniac. She's.... 22? I think? Ish? I'm bad at bday math. Anyway, Alecto is very much a purist, but the Carrows are poor and those mudbloods take our jobs and they are dangerous. Basically she's white trash and resentful, so she kills people. She's also the resident demolitions expert of the DEs too. Not sure if she would know Rita, but she loves gossip.
Next is Remus Lupin, werewolf bb. He just recently got kidnapped by Voldie and tortured, but he's home now and a little shy. He also JUST got outed as a werewolf, so he is very nervous. However, he was outed only sorta. As in, it's still very much speculation, but anyone close to Sirius would know that Remus is the werewolf in question. My point with bringing this up is that I would totes be all about Rita doing some sort of scoop on him and Sirius or him at Hogwarts or something. Idk. We'd need to talk to Annie, and I'd need to explain things better than I am doing right now, lol.
