I can picture Sirius bothering Remus while he's trying to study , and Remus getting frustrated and saying "Dear lord, will you quit it??"Sirius whips around and looks at James "Deer lord , you say?" James transforms and Sirius conjures a crown onto his head, then starts loudly worshiping Prongs as he struts around. Remus just sighs exasperatedly, trying to stay mad but unable to help smiling.
