Memories surfaced, excruciatingly painful ones where she witnessed Death Eaters punished by being skinned slowly as her sister reveled in it. After she came back from her time in Azkaban, she went so far as to eat the flesh she removed in front of the victim. Severus had his wand-arm skinned entirely for waiting to return to The Dark Lord on Dumbledore's orders as Bellatrix was slurping on the dermis like wet noodles. I shuddered and thought I'd lose my lunch if I had eaten anything.
