Before 7:00
Making sure the booze was properly delivered and then hidden until later, Bellatrix arrived and helped Romilda, who she has taken to calling Ro, set up.
She didn't get invited out often so she made sure to dress up nice. She wore a white dress coat with a black scarf, a warm pair of charcoal leggings, and a pair of tall black leather boots.
Genuinely she was happy to be there, make small talk and make a new friend.
