Theme # 3: Transfiguration
Professor McGonagall cleared her throat.

"Sorry, professor," the fifth-year mumbled. "It won't happen again."
The Transfiguration teacher turned away, and the green-eyed girl looked at her hands, certainly not too happily. She did not see his lips curl into a grin, did not see him lean back in his chair to inspect her, but maybe it was better she did not - he gave her toothache.
Err, heartache.

"Leave me alone, Stella."
Stella Williams raised an eyebrow. "Why the heck are you so tangy, today?"
She made to turn away - nearly walked into Oliver Wood.
He grinned.
