Marguerite gave Shepard a low bow. "A gentleman, I see. No wonder Garrus likes hanging around with you. He is a gentleman as well" she answered. Then she leaned up towards Garrus and whispered in his ear. "I will make it up to you later, I promise". And then she kissed the side of his neck, before leaning back down off her tippy toes.
Kaidan was impressed. It seemed that Garrus had found someone and that was nice because of course he wanted his friends to be happy.
