I truly believe now that Jim being shorter than Spock is a universal constant. no matter who plays him, they are always going to be shorter than their co-star playing Spock. No mattter the gender. Chris Pine is six foot tall. Zach is six foot two two (and I am just saying this because I looked to check up how tall Jenny Mills is for a short strip of text) and it came to me that since AOS McSpirk is all in the six foot range that TOS McSpirk would be making fun of the situation.
How about for a drabble: "We can't leave him behind"? Whatever ship you'd like.
