Or at least a line of dialogue addressing that however unconventional it was, everything they have been through showed them life is short, family is important, and that it was a choice they were actively making.... Kirk making a joke at Spock about their being two Captains on board, with Spock reiterating he never sought the center seat, that he is right where he belongs.... Sulu saying he can delay his own captaincy just a little bit more....Chekov joking that being first officer isn't all it's cracked up to be.... Maybe I'm a doctor, not a bridge officer....an aye Captain out of Scotty.... As they all choose their nontraditional path, together, for one more round....as a unit.
