Re: Would Spock Prime think Kirk and a young Kirk Prime look identical
In light of the original series, which featured Kirk and Spock going on landing parties all the time, it is hardly inconsistent.
As Spock was also senior science officer, his presence made sense, though you're right that it was probably standard practice to send both the captain and the XO on landing parties.
