Mrs. Scanzano is listed as Rosita in the credits, but is called Rosa by other characters.
Mr. and Mrs. Scanzano ride into town with the two boys to pick up supplies. They pick up the supplies, get in the wagon, and ride off. The boys are nowhere to be seen.
When Scanzano kills Hooker, Hooker's hat lands between his legs and the carpet is messed up. After Rosa and the boys enter the room, Hooker's hat and gun are visible a few feet in from of him and the carpet has been straightened.
