[Remus smile saddens, if such a thing is possible, considering the look on his face that already was there. He leans into her touch and squeezes her hand slightly.]

I've missed you too. [He says softly. He's been missing a lot of people, these past few days. Hermione, Harry. People that aren't here. People he suspects he'll never see again. People he hasn't seen in a very long while. He doesn't know why it suddenly hurts so much. It's been years, after all, you'd think one would get over these things eventually.

Unconsciously, Remus does not let go of her hand.] Surely you've got better things to be doing than wasting your time with your old professor, though.
