Hogwarts Professor, Swapped Bodies with Hermione

My name is Hermione. I'm a young witch just starting school, and suddenly I've switched bodies with a certain professor.

Damn it! Why am I watching my "self"

spin Ron around like a top and use the Hanging Jinx on Harry...

"Hermione Granger, one million points off!!!"

My name is Ryan, an outstanding Slytherin graduate and a newly hired Hogwarts professor. Suddenly, I've switched bodies with Hermione.

Snape: "What does 'Proposal for Reforming the Potions Curriculum' mean?"

"..."

Snape: "Why did you give Gryffindor so many points?"

"..."

Snape: "Thank goodness for that Hermione Granger. Otherwise, those stupid lions would definitely have won the House Cup!"
