All the swirling and zig-zagging he was doing was making Theo's headache even worse. But he wasn't gonna let that get in his way. His technique alone gained him another five rocks within two minutes.

Though he WAS very aware that all the other students were snatching all them up.

There'd BETTER be some left for him.
....

Stopping for another moment to check his cauldron, Theo BEAMED at the full eighteen rocks, big and small ones. How many were left? Four? Let's hope nothing, or no one would knock him off NOW.

Ding, ding. OH TWO MORE, and he didn't even try. Oh, sheesh.
