The Pitt Season 2: Everything you need to remember from Season 1

What a year it's been for The Pitt! The new HBO Max series, starring and produced by ER alum Noah Wyle, not only became a hit with critics and audiences, but also scored five Emmy wins, two Golden Globe nominations, and three Critics Choice Awards. And now this top-notch hospital drama series is back with Season 2.

Judging by HBO Max's "Top 10 Series Today" ranking on their app, lots of fans have been rewatching Season 1 in anticipation for the second season. The Pitt's been near number two all week, topped only by the internet's newest obsession Heated Rivalry.

But in case you don't have the time (or emotional bandwidth) to revisit all 15 Season 1 episodes of The Pitt, we're recapping everything you need to know.

How long has passed between Season 1 and Season 2 of The Pitt?

About 10 months has passed between seasons, with Season 2 taking place on July 4. Like last season, each episode of The Pitt Season 2 will be one hour in a day shift at the Pittsburgh Trauma Medical Center. This Independence Day setting means that on top of the everyday emergencies coming into the Pittsburgh Trauma Medical Center, you can also expect fireworks-related mishaps and other summer heat shenanigans.

But fret not! Attending physician Dr. Robby (Wyle) is working the day shift. He's re-teaming with a bunch of familiar faces from Season 1, including doctors Samira Mohan (Supriya Ganesh), Cassie McKay (Fiona Dourif), Mel King (Taylor Dearden), Trinity Santos (Isa Briones), and Dennis "Huckleberry" Whitaker (Gerran Howell), and student doctor Victoria "Crash" Javadi (Shabana Azeez). And their ability to pull together in the face of a crisis has been so satisfying in a world gone mad that The Pitt fans have described the show "competency porn."

Where's Dr. Collins?

In Season 1, Tracy Ifeachor played Dr. Heather Collins, a former flame of Dr. Robby's who suffered a miscarriage during her shift. From there, she understandably clocked out early, missing the flood of patients coming for the PittFest massacre. And she won't be seen in Season 2, as Deadline reported last July that Ifeachor would not be returning.

Does Dana come back?

Yes! Last season the charge nurse (Katherine LaNasa) with a heart of a gold and Yinzer accent threatened to quit her job after being attacked by a furious patient. Thankfully, Dana is back.

LeNasa won an Emmy and a Critics' Choice Award for her riveting performance in Season 1, so showrunner R. Scott Gemmill would be mad to write her off. And her return is good news for The Pitt, its fans, and Dr. Robby, who is the heart of the show, but also ever on the verge of bursting. Strong yet sensitive, sometimes raging but always resilient, it's impossible to imagine this place, or this show, without Dana.

Where has Dr. Langdon been?

In Season 2's premiere, The Pitt fans will see Dr. Langdon (Patrick Ball) return after some time away, as demanded by his behavior in Season 1.

At the start of that shift, Langdon was a respected (albeit arrogant) senior resident, entrusted to introduce second-year resident Mel King to the ways of The Pitt. However, as the shift goes on, he blows up at wannabe maverick Santos, sparking a lecture from Dr. Robby. Then, Santos shares her suspicions that Langdon is stealing benzodiazepines. When Robby confirms this, he is furious and sends Langdon home. However, when Langdon hears about the shooting at PittFest, he returns to help however he can. Robby reluctantly allowed it.

Now in Season 2, he's back and not the cocky bastard we remember. With a sheepish demeanor, in episode 1, Langdon returns from 10 months of "rehab and counseling." Some of the nurses welcome him warmly, while Mel is so elated she almost hugs him in front of everyone. But Robby is less enthused, relegating the returning resident to triage and otherwise trying to avoid him.

Santos is still calling Javadi "Crash"?

Yep. Within hours of meeting each other in Season 1, Santos had saddled her fellow student doctors with unwanted nicknames. Whitaker was mocked for being a farm boy with "Huckleberry," and Javadi was dubbed "Crash" for passing out during a particularly grisly medical moment. But by the end of Season 1, Javadi proved herself by making it through one hell of a first day, considering the PittFest carnage. She went out for drinks with coworkers in the park (don't tell her mom!) while Santos showed her softer side to Whitaker.

After being a jagoff to her peers all day, she discovered that Whitaker was unhoused and squatting in a closed section of the hospital. She offered him a room at her apartment for free. This was the most kind thing we'd seen her do yet, so there was the possibility Santos would be less of a bully in Season 2. But while Langdon is showing a newfound humility in this season, Santos is as cocky and cavalierly insulting as ever. She's still hyping herself up in front of superiors and undercutting her colleagues with snarky humor and antagonistic monikers. But even in this first episode, we're getting a better idea of why she's so determined to let no one get close.

Wait, where is Dr. Robby going?

Instead of walking to work, as we saw at the start of last season, Dr. Robby rides a motorcycle to the ER. Last season, Dr. Jack Abbott (Shawn Hatosy) did recommend to his stressed friend that a hobby might help him cope with hard days at the hospital. So, the three-month sabbatical Robby promises he's starting at the end of this shift will be a long-distance motorcyle ride far beyond Pittsburgh's iconic yellow bridges to Head-Smashed-In Buffalo Jump.

"It's an aboriginal UNESCO World Heritage Site in Alberta," Robby tells Langdon. "I've never seen the Badlands."

According to Head-Smashed-In Buffalo Jump's website, it's a place "that preserves and interprets over 6,000 years of Plains Buffalo culture. Through vast landscapes, exhibits, and diverse programming, learn about the cultural significance of this cliff to the Plains People."

So was Langdon right when he called this trip a "spirit quest?" We'll see.

Who is Louie?

While most of the returning cast from The Pitt's first season plays doctors, nurses, or other hospital staff, Ernest Harden Jr. played the lovable alcoholic Louie Cloverfield. Like Earl (Hansford Prince), who liked sandwiches but not egg salad, and Myrna (Jeanette Tondino O'Connor), who liked calling Dr. Robby "fruitcake," Louie is a bit of a regular around this ER. Like Norm from Cheers, except everyone keeps telling him to drink less.

In Season 1, Louie came to the ER twice in 24 hours with issues related to his heavy drinking. Langdon had prescribed him "benzos" to ease alcohol withdrawal, but pocketed several of the pills for his own use. In this new episode for Season 2, the pair are reunited, as Louie comes in with a swollen belly and an infected tooth. Langdon takes the opportunity to come clean, offering a sincere and unvarnished apology. While Louis is shocked, he offers forgiveness. And as was true last time, he may be suffering from his symptoms, but he's a ray of sunshine to all who cross his path.

The Pitt Season 2 premieres Jan. 8 at 9 p.m. ET on HBO Max, with new episodes each Thursday.
