Burnham recommends to Georgiou that she fire first -- and when the captain refuses, Burnham mutinies, briefly incapacitating her commander and attempting to fire upon the Klingons in what she claims is a maneuver she learned from, of all people, the Vulcans. This might prove to be the single most controversial sequence in the show: not only does a Starfleet first officer commit an act of mutiny, but she does so in the service of deliberately inciting a war (a Federation no-no) and justifying it as a Vulcan concept, something that the vehemently anti-war Vulcans might like to have a word about.
