"Ssh," she whispers, because she never knows how to take compliments from Jack, especially about her looks. It makes her weirdly self-conscious and that's the last thing she wants right now, while she's slipping off his tie and unbuttoning his shirt. There are differences between this Jack and the Jack she married--a little softer, a little grayer--but they are subtle and she doesn't care anyway, because he's still Jack (and God knows she looks a lot different than the Sam he's used to). She spreads her hands over his chest and pushes off his shirt and kisses him again before he can say something else.
