"Really now, come to life?" he responded with a grin. "My art has life all on its own, thank you very much," he said in mock indignance. "I'll come up with something..." The quill and notebook were quickly forgotten the moment Binns began his lecture. Twirling a drawing pencil in his hand he absentmindedly stared at the ceiling. The sound of Binns' droning just becoming indistinct. A couple of minutes later he didn't have any idea of what to draw but he had figured out where the charm went wrong, he'd have to fix that next time. His hand went back to the purple blob in his hair. He picked at it some more, hopefully he'd be able to get it out later without having to cut his hair. 

He took a look around the room, noticing for the first time that one of the Hufflepuff girls from the train was in there. What was her name? Constance, right. He wondered where her friend was. Likely Roxane had been in a different year. He made a note to catch her on the way out of class. He noticed on the guy next to him, slumped across his desk, having already fallen asleep. Across the top of his notes the word GOBLINS was written, nothing else. [I]Good as anything I guess,[/I] he thought. He carefully searched his memory for a good image of a goblin. He remembered a few from Gringott's, particularly Grunhok, his dad's preferred banker. He drew a quick sketch of the goblin, then repeated it a few times, the round head with pointed features pretty simple to reproduce. He then went through and fleshed them out. The one in front was clearly Grunhok. The rest all looked similar, yet they were clearly distinct. Most wizards tended to think all goblins looked the same, but a good eye and attention to detail would see they were as different as any humans. 

He worked to finish the sixth and final goblin, smiling as the thought of these goblins dancing filled his mind. He suppressed a chuckle as he gave the drawing one more glance. He took a quick glance around, Binns' nose in his book like always, the students all otherwise distracted, and the auror... well it didn't look like he was looking this way. What was he even doing here? No matter. He turned around and quickly slipped the drawing to Raymond. "Knock yourself out."
