P.D.'s Marina Squerciati Just Posted a Pic With 2 Med Stars—And Fans Are Stoked

PSA: Chicago P.D.’s Marina Squerciati hung out with Nick Gehlfuss and S. Epatha Merkerson of Chicago Med—and it was a lovely reminder of the real friendships that exist between the casts across the franchise.

Squerciati posted a photo to Instagram with Gehlfuss and Merkerson, teasing that both shows have resumed filming, which is exactly what viewers want to hear. 

“First day back and I came to the wrong show. Whoops. #chicagomed #crossover #firstday #wereback #chicago #nickgelfuss #onechicago #chihards @nbconechicago,” she captioned the shot. 

"LITERALLY TOO EXCITED FOR SEPTEMBER 21ST AND ALL THE BTS," one fan wrote in the comments. Another wrote, "We’ve missed you!" 

Thankfully, Squerciati found her way onto the Chicago P.D. set: 

In case you had your doubts, there’s absolutely no questioning how deep the friendships between the One Chicago family run, both on and off the screen. In a recent sit-down, Merkerson and her Chicago Med costar Oliver Platt bonded over some of their favorite moments from the past seven seasons. 

“[Our characters] have known each other for a long time, she’s known [him] through four marriages, and we don’t know how many children,” she said during a joint interview with Platt. "Plus we like to laugh.”

Platt agrees that their characters certainly have a special relationship, and when playfully prompted by Merkerson to describe their friendship using medical jargon, he couldn't help but chuckle.

“It’s very healthy,” Platt says. “It’s very dependable. It’s what makes the world go run for Chucky.”

Watch Chicago P.D. on Peacock and on NBC. Chicago Med is available on Peacock and NBC, as well. 

Both shows return Wednesday, September 21 on NBC.
