After Remus has unwrapped approximately half of the presents Sirius has gotten for him, Sirius excuses himself to start on the elaborate Christmas lunch that he has planned. Remus leaves him to it, putting his newly acquired things in the room that is slowly becoming more "Remus’" than a study. He then takes the next few moments of alone time to finalise his own gift to Sirius, one he has been working on for a while, secretly gathering photographs from everyone he can—he even contacted Dumbledore to see who in the Order might have some—and putting them into the photo album he bought.
