Katie’s scared. One minute she’s perfectly normal, knows who she is, remembers everything; the next, she can’t even remember how to make tea. What’s happening to her? She’s losing more of herself every day; how can he still want to marry her when half the time she can’t even remember his name?
But he holds her tight, keeps telling her everything will be alright, he loves her, wants to marry her. So she clings to him, wanting to believe him, but knowing deep down that whatever’s doing this to her, there’s no way to fix it; his promises are lies.
