Scrubs is back, and while the reboot is a hit with both critics and fans alike, it’s not simply a return to the same old story at Sacred Heart Hospital.

The major shift this season is an emotional one for the comedy, with things taking a turn after Dr. Cox, played by John C. McGinley, is diagnosed with microscopic polyangiitis, a rare and incurable autoimmune disease that can cause multi-organ failure. And in his case, the MPA has already started to cause renal failure, requiring ongoing medical intervention, and for Cox to lean on J.D. like never before.

ScreenRant‘s Ash Crossan spoke to the cast and show creator, Bill Lawrence, at PaleyFest last week, where they opened up about how Dr. Cox’s surprise diagnosis changes his relationship with J.D., and the impact it has on the entire hospital. For McGinley, it was a story arc that he was “thrilled” over.

John C. McGinley: Well, Zachy and Aseem pitched to me how we’re going to get you back … Because I was doing Rooster with Bill [Lawrence], and so I couldn’t be going there a lot. But then they said, “Do you think you could come back at the end of the season?” I’m like, “Yeah, what’s the arc?” And they said, “You’re going to get sick, so the mentor has to be taken care of by the mentees.” And I’m like, “Oh, that’s good. That’s rich. Writers can write that.” And they did. They wrote the heck out of it, and so I was thrilled.

The diagnosis shifts things on its head at Sacred Heart, with J.D., played by Zach Braff, stepping into the role of the caretaker for Cox, shifting the dynamic in the show’s original run, which saw Cox as Braff’s mentor. It was a conscious choice, however, with Lawrence telling ScreenRant it was an idea he “always wanted to explore” on the show.

Bill Lawrence: Look, I love the idea of the doctor becoming the patient. It’s something that we always wanted to explore on the show in the first place, and never got around to…

And while the diagnosis rocks the hospital, Lawrence promised that Cox isn’t going anywhere. In fact, he joked he plans to “blackmail” McGinley into doing as many episodes of Scrubs as possible.

Bill Lawrence: It was so … I don’t want to say funny, to me, because I understand the way TV works now, but my social media timeline was filled with people threatening me if I killed Dr. Cox — I’m not going to make it so John McGinley can’t be on the show. That would be insane … That would be crazy pants. And so I’m going to leverage him and blackmail him into doing as much Scrubs as he possibly can.

Neil Flynn, who plays the hospital janitor in the show, a.k.a. Glenn Matthews, echoed the same sentiment while calling the reveal of Dr. Cox’s diagnosis “very emotional.”

Neil Flynn: That would be a whopper, I think. They would only do it if John McGinley couldn’t continue with the show, or something. They wouldn’t. They wouldn’t kill me off. I wouldn’t think that would happen. But I thought it was very emotional, wasn’t it? I mean, it was nicely touching in those last few minutes of that episode.

Everything Else The Scrubs Cast & Team Said About Dr. Cox’s Surprise Diagnosis

ScreenRant: In the last episode, Dr. Cox is revealed to be ill. So how does that affect everybody around him? I mean, how did you react to reading that script or that moment?

Neil Flynn: Other sitcoms have done that in my life, and I’ve always kind of liked it. When it’s always funny, but then all of a sudden it’s a little tender, and you go, “Oh.” Because you care about the characters, and if they’re having an emotional moment, you’re with them. And Mr. McGinley did a great job in that episode. I’m sure he’ll continue to carry the ball for us.

ScreenRant: What was your reaction to just that storyline and how it will affect everything?

Judy Reyes: I’m interested in how it’s going to affect everything. I like the fearlessness of something like that. I think it makes sense that someone like Dr. Cox just can’t work in this environment because of how he is. He can’t really change. And he’s passionate enough about his work to not force himself on that ’cause he knows I can’t do that. I can’t call them girls’ names all day long. But I think that there’s going to be a way to continue to keep him engaged in all of this. We have to see that happen because that’s real life. That’s the other thing I was going to say. Bill is fearless about tackling real-life events. It happens. So what do we do, and what do we say? How do we laugh through it? All that stuff.

ScreenRant: We obviously have this big reveal of Dr. Cox and his illness. So tell me a little bit about the idea behind that and what that sets up going forward.

Aseem Batra: So we really wanted to find a way to bring him back into the fold after he kind of walked off into the sunset. And this gives us a way to have him back in our world, but in a different way, a way we haven’t seen this character before. He’ll still be grumpy, Dr. Cox, but I think we’ll see other angles and sides to him. So that was really the impetus for this whole thing.
