Molly worries for days when anything happens to a family member or someone she loves and cares about. Even when the situation is defused, she just can't help feeling panicked.
She stress bakes. When someone is hurt or sick, she'll stay up to bake their favorite cake, whether they end up eating it or not. It's calming.
She bakes whenever her children got sick, whenever someone got injured, or whenever something happened to Harry. She baked for Ginny when she got out of the Chamber of Secrets. She baked for Arthur when he was in St Mungos for the snake bite. She baked for Ron after the incident at the Department of Mysteries. She baked for Harry after the Triwizard Tournament. She baked for George after his ear was cut off.
She baked a cake for Fred. Chocolate with a hint of orange. His favorite.
Nobody ever touched that one.
Well that took a turn.
Let me know which characters you want a headcanon for next.
