His mom’s daemon died the day after the strange man came to give them the news about Jecht. The neighbours would come and visit, bringing them both food and attempts at smiles; sometimes, they would take Tidus aside and say, “It won’t be long now. Be strong for her.”
Tidus didn’t realise what it all meant until his mom slipped away herself; and in all the upheaval, he didn’t notice that the strange man, who had begun calling in regularly, seemed to have no daemon at all.
