Random thought but we know from Star Trek Into Darkness that augment blood regenerates cells from radiation damage, although somehow the Fed was not aware of this as Khan's blood regenerating a tribble was a surprise to McCoy.
We know Una is an augment. We also know her augment abilities include resistance to radiation. Pike knows he will have a delta radiation accident. He knows trying to avert things will harm the Fed and Spock. But what about going through with the accident, being wheelchair bound for a week, and then having Una's blood regenerate him?
We know Pike confided what happened to Una. How come Una hasn't thought of some way to use her blood to help Pike in the future? You think it would at least be mentioned. Or, considering how close Una came to being imprisoned, would her using her blood to try to help Pike out later on be some kind of violation of the Fed's strict anti-augment laws?
