"Put the man down." A voice comes over the now crowd as they all leap from their seats to the show of unexpected aggression within a normal social setting. Spock will worry of their whereabouts, and the different status of the ship, later. For now there is a liability on board by the name of Khan Noonien Singh.

"You are on a Federation starship, one that is different from the last, and you have no right to threaten a second crew now put the man down, Khan."

It took massive amounts of willpower, even for a Vulcan, to resist outright attacking him but the Khan he knows of was tucked away in cryotube with the rest of his people. Judging by the state of this man Spock discerned that he is either from a different time point, or he decided to start yet another coup which from the blood appears to have gone unsuccessfully.
