Bud's full formal name is used when he's introduced in church: James Anderson, Jr.
The word Bud stumbles over in his recitation is 'accoutered', a term often defined in the context of the equipment and armaments military personnel wear and/or carry into battle.
When the action spills over to where Jim is working at his desk marks the first time the viewer sees inside the Anderson family den, the room on the ground floor, off the foyer, at the foot of the stairs.
