Once again I have to say that I love getting glimpses into Mira's mind. (A 'look' inside Mira if you will). It was interesting that the Sharpling was able to recognize him for what he was to a certain extent.
As for the big reveal, of course I didn't see it coming. 214 years is crazy long. How did he survive? Was it intentional? Accidental? I have a feeling that the virus is most definitely a biological weapon and that there is a shadow government interested in it's development, cure and use.
Great chapter and thanks for updating!
