There is no explanation that he can offer Daniel that will be acceptable for why he has a pen and paper on him, so he ignores the questioning look and goes back to his coffee. Daniel has commanded him to eat-- not that he has the right to demand anything of him, but Lucifer will allow the transgression to slide-- and instead takes a tentative sip of the drink. It's bitter and warm and tastes a little like it smells, and he can feel the heat go down through his chest.

It's... pleasant. He does not mind the taste or the feel of it. It should make no difference to him; he views all food items as interchangeable, immaterial so long as they provide his vessel with the fuel it needs, but he enjoys this.

He drinks a little more before he pulls the packet of almonds from his pocket and opens them; he eats mechanically, as though food is just another necessary thing, with all the gusto that other people did their taxes.
