Emma explains that Josh has his own Facebook page. His future self has short hair and glasses (which Josh protests, because his eyesight is fine), and still lives in their hometown. Josh feels fine about this; Emma's the one who wants to move away.
Josh keeps referring to the makers of the website as "they." Emma corrects him and says that if it's true, technically Emma and Josh are the ones writing their own information.
They're now in the hallway at school and the bell rings. Before they go to class, though, Josh asks if the website said anything about his wife.
Begrudgingly, Emma tells Josh that he's married to a girl named Sydney Mills.
