" INT. DEFENSE AGAINST THE DARK ARTS CLASS—FOURTEEN YEARS PREVIOUSLY—DAY
It is Boggart time. DUMBLEDORE supervises the line of teenagers advancing to try their luck. “Riddikulus”—“Riddikulus”—gusts of hilarity as a shark becomes a flotation device, a zombie’s head turns into a pumpkin, a vampire turns into a buck-toothed rabbit.
DUMBLEDORE: All right, Newt. Be brave.
16-YEAR-OLD NEWT moves to the front of the queue. The Boggart turns into a Ministry desk.
DUMBLEDORE: Mmm, that’s an unusual one. So Mr. Scamander fears what more than anything else in the world?
16-YEAR-OLD NEWT: Having to work in an office, sir.
The class roars with laughter.
DUMBLEDORE: Go ahead, Newt.
16-YEAR-OLD NEWT: Riddikulus!
NEWT turns the desk into a gamboling wooden dragon and moves aside.
DUMBLEDORE: Well done. Good job. "
