This isn't her Eddie, not her Jake, but Susannah was once Odetta (Detta too, when she lets herself remember) and she knows about becoming someone new. As they head together towards a home she's never seen, her unfinished cocoa getting cold, the practicalities of her unexpected new life start to buzz against her head: she should see a doctor; she must find work, not live on the good graces of this man who isn't her husband.
Then Eddie smiles at her again. Another universe, another spoke on the wheel. It's close enough. She'll find a way. She takes his hand.
