"Oh dear..." she says softly, shaking her head a bit in confusion as if to clear it, "I've been so busy enjoying talking to you that I forgot just how much you mean to m- Kate...."

As she says this her gaze darts towards you once more and she shifts her stance a bit, taking on a subtle sultriness.
