You Don't Say
Hermione has a surprising answer to a question from Slughorn. Written for the challenge "called on in class when you don't know the answer" combined with Veritaserum ingestion.
Hermione licked her lips, remembering the odd not-water taste on the rim of the drink Ron had offered her at lunch, just before Potions with Slughorn.
Slughorn cleared his throat. "Who knows the core aspect of Sulphur Vive that makes it react with Sal Ammoniac to produce Panacea?" He winked. "And it isn't sulphur."
What the bloody hell...
Heartbeats passed before he turned to her expectantly. "Miss Granger?"
"I should just make something up since no one here - not even you, Professor - likely knows the answer anyway."
There was a collective gasp, and Hermione clapped her hands over her mouth.
In sudden gustatory recognition, she leveled an icy stare at Ron. "If you ever give me Veritaserum without my permission again, I will annihilate what little reputation you have remaining at Hogwarts."
Ron looked at Harry. "Er, she's saying that under Veritaserum, isn't she?"
"Yes, mate, she is."
