Re: Would Spock Prime think Kirk and a young Kirk Prime look identical
Although I'm inclined to agree with the "cross-temporal older brother" theory, because Chekov Prime never seemed to be anywhere near as much of a genius as his counterpart.
I've always thought Chekov was "book smart" but didn't have much in the way of common sense. Taking that into consideration, it's not hard to see how he managed get himself into so many trouble spots.
