Cora

Cora is a cousin of Arthur, Kate, and D.W. Read's. She was the original flower girl in Aunt Lucy's wedding in D.W. Thinks Big. In I'd Rather Read It Myself, a look-alike of her was seen during D.W.'s imagination about a girl named Agent B.W. in the wedding scene where B.W. retrieves the ring.

D.W. Thinks Big
In "D.W. Thinks Big" Cora is Arthur and D.W.'s cousin who comes with her mom Jessica and dad Richard to stay with the Read's for Jane and Jessica's sister Lucy's wedding. Cora is the flower girl for her Aunt Lucy's wedding and because of this she tends to be a bit of a show off like telling a jealous D.W. that the wedding can't go on with her. She also shows D.W. her locket that Aunt Lucy gave her which she accidently breaks and blames it on D.W. Cora shows her mom the locket and Cora's mom tells D.W. not to play rough with Cora's locket even though D.W. didn't do anything wrong. That night Cora sleeps in D.W.'s bed while D.W. sleeps on the floor but Cora asks her mom if she can sleep with her because she hates D.W.'s room and that the awful colors hurt her eyes but her mom tells Cora that she's just tired and needs her sleep because she has an important job in the wedding tomarrow to which Cora replies That's right. I do. The next day when the flowers arrive D.W.'s mom puts Cora's crown on her head and Cora's dad takes a picture of her. At the wedding when Cora arrives she shows off by saying I'm here everybody! I'm here! And Grandpa Dave takes Cora to get her pictures taken with the rest of the people in the wedding. After getting their pictures taken Arthur(who is the ringbear) and Cora walk down the aile but before they do Cora warns Arthur not to make a mistake because if he does he'll ruin the whole wedding. While they're walking Cora tells Arthur to smile but Arthur accidently loses his balance and throws the wedding ring into the air and it lands in the piano's pipe organ. Arthur volunteers to go in and get the ring but can't fit in the organ because of his size so Grandpa Dave suggests Cora but Cora says no because it's dirty in there and asks if they can get another ring to which Cora's Mom approaches her and takes her away telling her that she doesn't have to go into the organ. Finally D.W. volunteers and manages to fit in the organ and bring the ring back out. Because of this Arthur lets D.W. carry the ring and Aunt Lucy takes off Cora's crown and puts it on D.W.'s head making D.W. also the flower girl. At first Cora starts to complain but when Aunt Lucy says her name Cora says All Right and allows D.W. to be the flower girl too. At the end Cora is seen waving good-bye to Aunt Lucy and her husband as they leave for their honeymoon. Cora isn't seen in anymore episodes after this nor is she mentioned by any of the characters.
