Want to see what’s coming up in the next episode of Chicago Med? Look at this week’s scenes with our Chicago Med season 4, episode 7 photos.

The next Chicago Med is going to feel like its own crossover episode, based on the promotional photos that NBC has released for Wednesday’s installment!

Wednesday’s episode is called “The Poison Inside Us” and deals with the release of some deadly chemicals inside the Emergency Department. With such a dangerous situation on their hands, the images show that the doctors at our favorite hospital called for an awful lot of backup.

Fans will be able to spot both Chief Wallace Boden (Eamonn Walker) from Chicago Fire and Hailey Upton (Tracy Spiridakos) from Chicago PD in the below photo gallery, making this an episode that involves all three One Chicago shows.

They may not be the only characters crossing over, either; sometimes crossover appearances are not included in the photos, so keep your eyes open for other Chicago PD or Chicago Fire heroes as well! But from what we can see, this is going to be a very intense episode with a lot of characters involved.
