I thinks this is distilling into Mitchell. JJ has gone down the TOS movie route in picking a canon character for his second movie.
We were told eons ago to expect canonical characters.
This comic mini-series is a prelude to the movie, and supposedly ties in to to "Star Trek Ongoing", which has already done the Mitchell story. If Uhura goes silver-eyed in the prelude comic, she will be back to normal by the new movie.
