Re: (Possible Spolier) Clip#3 'I Allow It': Kirk and Harrison.
Taking the 'setup' material from the IDW comic, the new video game and Countdown to Darkness into account, I've (got no spoilers, I'm just guessing) got the terrible feeling that the 72 'reasons' Harrison is referring to is 72 double agents. 72 members of Section 31 among the Enterprise crew, or whatever the outfit is called that Harrison belonged to.
And even worse? One of those 72 is sitting at the Enterprise's helm.
