Devlin is a girl, but in your eyes a bad dog. She is now chained away in a dark and bitter prison because of you. She was a wild girl in the woods, just living out her best life until you came along seeing her as a rabid dog that barred its teeth towards you, so you locked her away because you can't have a bad dog in your eyes. Devlin will always be violent, even if she was freed because you can't take away the only instinct that kept her alive.
