Where do people get the idea that Johanna's family were killed because she refused prostitution, and that this is confirmed fact?
A クイズ 質問 of mine was recently deleted after someone コメントしました that it was incorrect, that Johanna's family were killed on Snow's orders because she refused to be sold. The commenter 発言しました that the information came from hungergameswiki and that it's from Mockingjay.
But I've just read through Mockingjay and I can't find any mention of this. When Finnick reveals the truth, he says it happened to others too but doesn't name anyone. Haymitch only says he was the warning to victors like Finnick and Johanna and Cashmere. The only time Johanna mentions family/loved ones is in Catching 火災, 火 after the Jabberjay attack, when she says that there's no one left she loves. She doesn't say they were killed または give any details.
Where did this idea come from? Was it confirmed in some interview または something of that sort? または is it 人気 fanon/headcanon?
