If fans of "The Pitt" struggled to get through the first season without feeling some second-hand anxiety for the doctors of Pittsburgh Trauma Medical Center, the second season might just send us all into a full-blown panic. How the show is going to outdo that kind of intensity with its second season remains to be seen, but everything points toward an even more fraught 15 episodes. But with the return of Patrick Ball's Dr. Frank Langdon following his mandated stint in rehab, there's sure to be plenty of fireworks between him and Dr. Robby. Otherwise, "The Pitt" season 2 trailer confirmed the return of several fan-favorite characters, so we'll at least be in familiar company for the most part. But there is one other storyline involving a baby which, apart from sounding like it has the potential to be the most tragic narrative thread yet, almost made things behind the scenes as dramatic as life in a real emergency room.
