Moment 12: The Potion

Late in the night, Snape and his student helper were working over a bubbling cauldron, sweating and irritable.

"Professor, no, that's the last ingredient. It's probably supposed to be green!"

"Miss Granger, I think-" But he stopped. The potion had turned the tell- tale oily black. Snape turned away to hide his tears.

"Professor-" Her voice was cracking. "I think- I think that we- you- did it!"

"You are dismissed, Miss Granger." His voice was unsteady, but it was clear she wasn't wanted.

"Sir-"

"Please go."

As she slipped out the room, Snape's wrenching sobs were left to proclaim their achievement.
