Kirk, from the guard station, scowled at Spock's words. In another universe, Spock really did turn traitor to him and got rid of him. It sent a shiver up his spine, thinking about the conversation in his quarters, the feeling of fear/digust/traitor from Spock's mind, and hoped like fuck it wasn't a sign of things to come.

Did he learn all of that from Marlena? Well, he was right if he did. She did open up to him. Hope she will when he goes to talk to her.
