"For Goodwin, it's always what's going on in the hospital, taking care of the hospital," said Merkerson, referring to her character, Sharon Goodwin, when asked what's in store for the finale. "We have a prisoner who's come in, a very dangerous man who's suffering from dementia. So the question is what to do with him. And then, you know, Goodwin has a love interest. So we have to figure out what's going to happen there."

Next up, it was Mayo, who revealed the Chicago Fire finale is "basically a love letter to our dear Chief Boden," played by Eamonn Walker.

"Eamonn Walker was the first character cast in Chicago Fire, in any of the Chicago universes. So we get to see him in a rescue in a way we never have," Mayo told Jimmy Fallon and The Tonight Show audience. "The new member on truck, we finally get to find out what his secret is. He's been holding a secret, he's been having secret conversations on the telephone. Thinking that he's keeping it low key, no, we find out."
