Gellert had been expecting Remus to come by eventually. It would be unavoidable, after all, given his unique position in the Healing staff and his own contribution to Gellert's recovery. Albus had given Gellert a full enumeration of every act taken to preserve Gellert's life, most especially of the procedure suggested by Lupin and the details of its implementation. It would have been absurd for Lupin to be shouldered out of his position now that Gellert was certain to recover. Gellert had already considered awarding Remus some sort of medal or certificate. Nothing public, nothing sensationalised--after all, it would be unwise to lift Remus into an overly-visible position too soon--just a private recognition of his service to the wizarding world.
He had been reviewing some of the reports regarding the state decisions Albus had been forced to make in his absence when Remus knocked. Gellert had sensed Remus's presence, his unique magical signature, as he approached the room--and he sank back against the pillows, letting some of the energy drain from his limbs so as to appear slightly less well than he actually was.
"Good afternoon, Remus," Gellert said after Remus closed the door behind him, his voice soft but not broken.
