Continuity mistake: When Danny finally gets out of the panic room and Jerry throws him the phone to call Stella, the phone disappears from Danny's hand and then reappears in subsequent shots.
Revealing mistake: When Messer is trapped in Mr Hudson's safe, the newspaper clippings he pulls out from the drawer show obvious Latin dummy text in the articles, while the headlines are in English.
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.
