"What's wrong with you?" Mia hissed, smacking Sirius's arm. "How did you get him
to partially shift?"
James blinked, raising one eyebrow in confusion as he swallowed his bite. "Shift?"
"It's not a shift. I will admit, that's what gave me the idea. Just a hex. I, personally,
think his hair looks much better like this," Sirius said with a beaming grin.
At the mention of his hair, James dropped his scone and tried to investigate by
touch, only to find two large antlers sticking out of the top of his head. "Padfoot!" He
launched forward, knocking Sirius from his seat and onto the floor. The two boys began

away, she pulled timetables from her robes and began handing them out. "I hope you'll put
more effort into my class this year than you've shown this morning."
"Minnie," Sirius called after the professor as she walked away from the table, "I
think you're flirting with me! You know how I love it when a pretty witch gets mad and
scolds me." He tucked his timetable into his pockets while ignoring the fact that James was
still struggling to get out from under him. "Love that old bird. If she were forty years
