A Talionic Tonic (PG; Severus/Hermione/Luna; 100 words)
Hermione had expected Severus to be happy about their news, but joy wasn't an emotion to which he had yet become accustomed.
He'd better get used to it, Luna thought, angrily chopping Glumbumble parts while Severus drank and Hermione cried.
She'd dose the tea in the morning after she and Hermione had taken their share of it; Severus never rose early, and he'd need her talionic brew far more than any hangover potion.
It would make him feel what she and Hermione were feeling.
Which should help him behave with a bit more sensitivity towards the mothers of his children.
