It’s not taking long for 9-1-1 and 9-1-1: Nashville, airing back-to-back on ABC this season, to cross over; the latter is still in its first season. And when TV Insider spoke with the spinoff’s showrunner, Rashad Raisani, about the midseason premiere, we, of course, had to get some scoop on Oliver Stark and Ryan Guzman‘s trip to Music City.

“It’s a ton of fun, first of all. I mean, the guys are great. Buck and Eddie are the ones coming and couldn’t be two better characters and two better people, two better actors who are just — wonderful chemistry, wonderful guys, and just brought a great sense of life and fun to our [show],” Raisani shared.
