Visible crew/equipment: While Elise is telling everyone about Bay Mirror's new owner, Jason Dean, just as she warns them that he's known for shaking up companies, we can see the white T-mark and a bit of the yellow tape mark on the crew's black mat (which is gone in following shots) at the lower left of the screen.
