Chicago PD may be taking the week off, but one of its most popular characters will appear on FBI Season 2 Episode 19, airing tonight on CBS at 9/8c.
CBS has now released a new trailer for the milestone episode tha brings a character from the NBC series over to the Eye network.
It all sounds confusing, but Dick Wolf is being the FBI universe, as well as the OneChicago universe, so he made it happen.
For now, we know Tracy Spiridakos is headed to New York to serve a temporary assignment at the New York Bureau of the FBI.
“Tracy’s character is a fan favorite, and I’m extraordinarily happy to be shining an even greater light on her and gaining new fans along the way before her return to Chicago P.D," Wolf said when the crossover was made official.
It will undoubtedly put Hailey Upton in a difficult situation, working with people she's never worked with before, but she always rises to the challenge.
Given the reason Hailey was sent to New York, it certainly makes you wonder what could be on the horizon for the characer.
Is it possible that Spiridakos could become a more permanent fixture on FBI? Only time will tell.
Another thing we know about this episode is that it is directed by Chicago Fire grad Monica Raymund.
So, there will be a Chicago Fire favorite behind the camera, a Chicago PD favorite in front, and all we need is a Chicago Med actor in there somewhere.
Here's the latest trailer for the episode, which shows Upton's first moments on FBI.
