So its NOT Khan? That bodes well!
One preview said that Cumberbatch's mystery villain approached the family at the hospital offering "healing abilities" to help with their daughter. Which character, if they are, from the series had those kind of powers or access to them?
EDIT: Admittedly, it did remind me of this
, but that doesn't really rule out any other kind of healing powers that could be found in the Trek universe.
