From the scene where Wyatt brings Callie and Brandon donuts in the kitchen, when Wyatt says "I brought donuts" and Brandon moves his head out of the frame a crew member can be seen sitting on a chair in the back of the kitchen.
When Wyatt brings in donuts about midway through the episode, there is a woman visible sitting on a bar stool to the right of the shot. She doesn't appear to be a character and has no lines.
