"You are so serious." She's just making an observation, opening the small package - the tentacles (three of them, relatively small, dark blue-green) react to the motion and the change in light, reaching for and recoiling from her fingers in turn as she fishes the tie-pin that they're attached to out in the grip of her thumb and forefinger.

The fact that Rodolphus isn't actually wearing a tie is not going to thwart her, the pin will attach just as well to his robe and she sits forward in her seat to reach across the table and achieve this, adjusting the sit of it a few times until she's sure that it's secure. She flicks her fingers at the tentacles before she takes her hands away from him, settling back in her seat and picking up her coffee cup, cool as you like.

Is there a good response to 'I saw these tentacles and thought of you'?
