My impression of Beyond's Spock is ... no. With the possible exception of Uhura, Spock would have let any (and all?) of the crew die in the volcano, or any other circumstance, to avoid violating the PD. Credit where due, he would have followed his oath. My theory is whatever Losira/computer use to send the Enterprise a near thousand light-years away was still there (lingering subspace conduit?), and the Enterprise as following back to the planet. Which accounts for the the unusual covering of distance for a given period of time. nu-Khan made it in less than one minute. What does god need with a starship? Better question would be, what do Humans need with starships anymore.
