Paige claims she has made an appointment for Emily this afternoon to see him in Philly. Emily doesn't see swimming in her future, but Paige convinces Emily to consider all of her options. She says Emily can take a year off of college to train instead of going to a state school she doesn't want to go to. Emily, hesitant, reminds Paige that she can't swim, but Paige says that it's not forever. Emily agrees to go, if it means she could spend her college years with Paige.
