The girl that Day's rescued isn't going to tell her his name, which is fine since Day sure isn't going to give away his name either.
Day is kind of upset because he lost the bet and now can't buy plague cure, but Tess really wanted to save the girl.
They camp out in an abandoned library and Day finds himself checking the girl out some more even though he's mad at her; he even thinks about kissing her.
They talk a little bit and the girl says that she's from the Tanagashi sector and travels a lot.
While Tess stays with the girl, Day sneaks out to check on his family.
When he sneaks in, he overhears John and Mom talking about Eden and how he's not doing very well—the plague suppressants aren't doing much for him.
Day is outside when he finds a number inscribed outside: 2544. He frowns and wonders what it is.
