Being stuck here for many years has put torment on her mind, maybe just a teansy bit mad. She often sung to herself to pass the time, chattering with the Weeping Angel statues that filled the room. They must’ve had pity for her, for they never attacked. They often just sat next to her in silence, frozen in their own stony prisons, molding and freezing more with each day. She’s very self deprecating and blames herself for her banishment.
