The Pitt

With the Pitt down a staff member, Robby relies on his team to pick up the slack. Later, Santos finally voices her suspicions.

As Collins guides a surrogate through a difficult delivery, Robby does his best to keep a developing staffing situation under wraps. Meanwhile, McKay confronts her ex's overstepping girlfriend, and Whitaker watches Samira sniff out a drug-seeking patient.

As dozens of critical patients flood the ER, Robby and his team struggle to keep up amid quickly diminishing supplies. Later, Javadi's fast thinking impresses a key surgeon, and Mel keeps tabs on an injured mother and son.

As the night shift begins and the death toll rises, Robby refuses to give up on a mass casualty victim – even after Abbott intervenes. Unable to find an attending, Santos and Samira each attempt risky moves to save their patients' lives.
