Bellatrix Lestrange wore her scars with pride. They showed how she had suffered for her lord and how faithful she had remained. She had not ran and hid like so many others of the Dark Lords supposed "faithful" inner circle had, she had stayed true to him consequences be damned.
Her scars all showed that she never betrayed he Lord and for this she was sure that he would value him above all others. As she lie huddled in a corner of her dank cell in the wretched place they called Azkaban an insane giggle escaped her lips, when her Lord rose, and she knew that he would, she would be rewarded. Her scars were physical proof of her loyalty and that lone thought kept, for the most part, the chill of the dementors at bay.
