The 'Law & Order: SVU,' 'Chicago Fire,' And 'Chicago P.D.' Crossover Episode: See What's Ahead Romantically!

This week is the Law & Order: SVU, Chicago Fire and Chicago P.D. crossover and there are a lot of different storylines coming into play. In addition to the different characters crossing over this week, will there be any relationship crossovers? Maybe!

Chicago P.D. detectives Erin Lindsay (played by Sophia Bush) and Jay Halstead (played by Jesse Lee Soffer) have been walking the line of a possible romance this season, but the crossover won't be the tipping point, unfortunately. "It's tested a little bit, as you might imagine, because they're out of town. But there's no crossing the line-yet-for those two," executive producer Matt Olmstead told TV Line about the pairs trip to Law & Order: SVU.

When Olivia Benson (played by Mariska Hargitay) heads to Chicago P.D. her interaction with Hank Voight (played by Jason Beghe) is another interesting duo to keep an eye on this week. "When Voight sees her, there's a smile on his face," the P.D. executive producer explained. "He's happy to see her. Because there's this immediate chemistry, immediate tug [and] shared affection between two very similar characters, ironically, though they may have different backgrounds and different approaches."

The crossover will also show Hank coming to New York for SVU and Olivia is the first person to put him in his place. "Voight basically barges into an interrogation in New York and gets a little physical," SVU executive producer Warren Leight told TV Guide. "Olivia comes in after him and says, 'You pull that crap again, and I'll put you in jail.'"

On set, the vibe was completely different as the casts of every show bonded and worked extremely well together. "One thing that I didn't really expect was the camaraderie with the actors," Matt told the publication about filming the three-way crossover.

"You never saw actors standing by themselves, waiting for their line. They were always in groups. They hung out as a group after they filmed. There was a lot of travel and working weekends, but the feedback I got from everybody was what a special event it was for them just as actors."
