Continuity mistake: After Danny assists Lindsay with the multiple footprints issue, when Danny gets the phone call from Don, his dark shirt's right sleeve is unbuttoned and loose, but it cuts to a wider shot and suddenly his dark shirt sleeve is buttoned up, covering his watch and the white shirt. (00:26:40)
Chosen answer: Probably to broaden the scope of the show's plot and give the audience a chance to see the characters in a different setting, People act differently at home from the way they do at their workplace. By the ninth season, the characters would have become overly familiar and predictable. It gives the writers a chance to do something different with them.
