"I promise." She had to say it halfheartedly. This could be a 'white lie' whether he likes it or not. She hoping this can make Alexander's tense face to calm down again but it didn't happen. She knows, he knows very well that she will never do that. Breaking a promise is not that hard after all!
"You, make sure she keeps her promise."
