To me, it was simply a poignant moment, from a scene I have always liked in an admittedly 'less-than' among fans film, and I DID take it as something Kirk intuited. McCoy and Spock certainly seemed to take his feeling seriously, if Bones was reacting in what may have been a 'creepout' moment, and after all, he almost did see his dear friend die earlier that day. As far as it contradicting the death in STG, well, it's not a biggie to me. The fact Jim died is more important.And unfortunate.If befitting him.
