As Arthur prepares to undergo heart surgery, he asks Carrie and Doug to bring him his sleep mask. While digging through Arthur's closet for the mask, Carrie finds a box which contains an extensive scrapbook of her old finger-paintings, report cards, and school photos that Arthur has been keeping. As she is flipping through it, she finds an acceptance letter from Florida State University – which she has never seen before. Meanwhile, Doug makes friends with a quirky stranger in the hospital and soon regrets it.
