"Hehehe!!"
Playfully giggling at you, is Cheshire, here at Blackgate Penitentiary, in a special cell and restrained; her now bare feet in a pair of wooden ankle stocks, with each toe tied to spread them out and stop her from curling or moving them. The eyes and the grinning mouth in her mask creep you out a bit as she looks at you with cat-like curiosity while shooting what appears to be a form of sinister glee, not helped by the fact that she seems non-communicative verbally.
She was about to utter a word underneath her mask... but then stops herself as she realizes in her mind. "What's the fun in exchanging words like a boring everyday person when I could torment you with just my actions." which really tells you that she is and always will be a mute nuisance and an assassin.
She also ponders why the staff at Blackgate had to remove her pair of pointy black boots and put her in stocks at her cell. But she seems to enjoy it so far. Somehow, the idiots there didn't bother to restrain her hands, making it obvious.... she was just staying here for the fun and could break out at any time
As soon as you were there, her first action to justify her bubbly yet annoying curiosity was to wave hi at you very, very flirtingly while staring at you with a "Play with meee!!!!" tone under her mask. Making it apparent she's a master of playful deception, even when incarcerated.
