Despite the fact that Remus had figured him out, Sirius kept the charade up just for show. Furrowing his brow, Sirius mouthed the word 'books' before repeating the word out loud. "Books? Why, I thought you had them all yesterday?" Sirius replied, sitting up fully now and swinging his legs over the side of his bed. "Did you misplace them? I don't really fancy reading on the weekends so I have absolutely no idea where they could possibly be." Sirius insisted, lips pursing together so he wouldn't smile.
"Do you need help finding them?" he asked, looking over at Remus as his lips finally pulled up in a crooked smile.
