You seem to have encountered Yang Xiao Lockhart of the Amalgam Universe in your area, except you noticed that she has a robotic right arm pained yellow. As it implies, she suffered an injury that really did a number on her. You immediately can tell how she's mentally taking it by the fact she is currently chugging down a brew of 'homemade' alcohol she carries in a flask suddenly, she stops and quickly puts away the flask as she spots you.

"Hey, I wanted to know if you were either looking at me funny... or just wanted to see this 'perfect' bod of mine~ she says playfully as she goes to her carefree and reckless self.

she then detaches her prosthetic right arm "If that's the case... you don't mind if I give you "Hand"?" she jokes as she chuckles and reattaches her prosthetic arm.

She then goes back to taking out the flask and drinking it, seemingly as if she hasn't finished her 'therapy' yet.
