Biding time for Derek was an ease feat. He was patient, to a point. He honestly didn't have to wait as long as he thought to be noticed in his feline form.
All the more fun for him later on.
A ginger kid seemed a bit confused to see a cat on Hogwarts' soil. If felines could scoff he honestly would have. Out of everyone that could have noticed him it seemed like a first year with no intellectual ability found him. Great. The sleek obsidian colored cat swished his head, leaning forward as his bright yellow eyes gazed over the form of the ginger that knelt to the ground and began to dig something out of his bag.
Curiosity killed the cat, but God damn it this would be a suicide mission at this rate.
Derek tentatively stepped forward to see the child ripping off something that smelt oddly like cauldron cake-- Derek mewled, a noise he couldn't honestly believe he made but, Jesus, cauldron cake? That stuff was fantastic and the kid was just handing it out to random strays?
...Did he just get found by a Hufflepuff? They were good finders after all. It honestly wouldn't have surprised him as much as it should have, honestly.
"Meow?" The cat spoke, walking and sniffling towards the assumed Hufflepuff. He kind of really wanted the cake now... Get your head in the game, Derek. He fussed at him self, cutely tilting his head and looking up to the ginger. With a tiny, almost shy mewl his mouths moved a bit closer to the cake. With a small bite he darted forward, brushing his face against the boy's soft skin. With an explosion of a purr that rumbled through his entire being he just knew he'd won his room.
