If in one of the episodes they show Spock, should they use Zachary Quinto?
Yes, I know this isn't set in the Kelvin timeline, but even in the prime timeline I accept that when Spock was young he looked like Zachary Quinto. Why do I think this? Because in Star Trek: Beyond Kelvin Spock looks at a photo from prime Spock's timeline which shows a picture of Kirk, Spock, McCoy, Uhura, Chekov, Scotty, and Sulu circa Star Trek V. Thus, I also accept that once the Kelvin Enterprise crew become older they will look like Shatner, Nimoy, Kelley, Nichols, Koenig, Doohan, and Takei.
