She Panics
The woman seemed to panic all of a sudden. She appears to be hearing noises coming from the rest of the home. And she can be seen running off to a hiding spot just off-screen minutes before Joe enters the kitchen.
Joe Gets Back
Joe, who appears to be oblivious to the drama, pours himself a drink before retiring to bed. Once he is out of the way, the lady emerges and resumes her foraging activities. Finally, she returns to the stool and exits the area through the crawl space above.
