Visible crew/equipment: When Delafont tells Mac, "None of it would have happened if he delivered what he promised," Jo figures out the connection between the cases. It then cuts to Jo with the Post-its, and at the start of the following wide shot, as she turns to walk over to the computer screen with suspects, a red T-mark is visible on the floor. It becomes visible again in a following shot. (00:35:30)
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.
