Aurors surround the entrance to the subway. Pointing their wands at the pavement and into the sky, they draw an invisible energy field around the entrance.

We hear more Aurors arrive, among them Graves -- scanning, calculating, and immediately taking charge.

GRAVES: "Bar the area. I don't want anyone else down there!"

EXT. SUBWAY ENTRANCE -- NIGHT

As the magical field is almost complete, a figure rolls underneath it and dashes unseen into the subway -- Tina.
