Mia had always tried to keep on top of her health—save the one year she had lost
sleep due to stress over spying on Slytherins. She had known her limits because she pushed
them too far during her original third year.
As expected, Remus found the little witch slumped over an Arithmancy tome so
large that she had to have used a Feather-light Charm just to pull it down from the shelves.
He frowned at the sound of her softly snoring, knowing that he would have to wake her.
She would surely go into a fit knowing that she had missed a lesson.
He sighed and looked at the small puddle of drool on her book. Wincing at the
sight, he silently and delicately Scourgified the book before she could wake up and see that
she had slobbered over a three-hundred-year-old text.
Remus sat down in the chair beside her and put a gentle hand on her shoulder.
"Hermione?"
Slowly, chocolate brown eyes opened to look up at him. There were dark circles
beneath those innocent eyes which made him cringe in concern for her. Hermione,
unfortunately, must have taken the look on his face to be anger, and she jumped up.
"Oh! Professor! I'm so sorry! I didn't mean to fall asleep in class!"
"Hermione." Remus tightened his grip on her shoulder to prevent her from moving
too quickly. "You're not in class; you're in the library."
"Oh... I.. ." Hermione glanced around at the table confused, as if she had
forgotten what she was supposed to have been revising.
"You need to go back to the tower and catch up on some sleep."
"No, no." She shook her head, stifling a yawn. "I need to... revise... for Charms."
Remus winced, not wanting to tell her that she had missed Charms. The thought of
doing so flew right out of his head when she reached up to cover another yawn, wincing
in pain as she moved her hand.
"Hermione, what happened?" He reached out, tenderly taking her small hand within
his own. A large bruise encircled her entire thumb, extending up past the wrist. "Your
thumb is broken."
She looked guilty.
"What happened?" he asked again.
"I broke my thumb."
