Chicago Fire's Alberto Rosende Leaves Series After Four Seasons As Blake

When Alberto Rosende joined the cast of "Chicago Fire" in Season 8, his character, Blake Gallo, was a brash upstart. Gallo and his fellow newcomers Violet Mikami (Hanako Greensmith) and Darren Ritter (Daniel Kyri) were primed to be the next generation of Firehouse 51. Now, Deadline reports that Rosende's time on the show is coming to an end after four seasons.

Rosende made his "Chicago Fire" debut in an episode titled "A Real Shot In The Arm" and he was quickly promoted from a recurring character to a series regular in 2019. It was soon revealed that Gallo's journey to Firehouse 51 was a personal one; as a child, he lost his sister and parents in a fire.

Gallo wasn't a fan favorite — many viewers found him reckless and immature. Still, the character grew during his time on the show. "I think one thing we've seen Gallo trying to learn over the course of these three seasons so far is how to take all his unbridled passion and energy and excitement and shape that into being an exceptional firefighter," Rosende told NBC Insider in 2022. In Season 11, Gallo fails to talk a jumper down from the roof of a building. "I do think this will be one of the more grounding things we'll see Gallo go through," Rosende continued. "That puts Gallo on the path to being a better leader. A better member of the firehouse. A better person."

Alberto Rosende's "Chicago Fire" departure is just another reason Season 12 will look different. Earlier this month it was confirmed that the upcoming season will be the last for Kara Killmer, who has played paramedic Sylvie Brett since 2014. There are changes behind the camera as well. Season 12 will be helmed solely by showrunner Andrea Newman, whose co-showrunner Derek Haas exited the series in 2022. That said, it's not all despair in Firehouse 51. Next season, Taylor Kinney is returning following his lengthy Season 11 hiatus.

As for Rosende, his departure from the series was reportedly amicable. In all likelihood, the actor is looking to add some more projects to his resume. Prior to "Chicago Fire," Rosende appeared in episodes of "Blue Bloods" and "Law & Order: Special Victims Unit." Between 2016 and 2019, he portrayed Simon Lewis in the Freeform drama series "Shadowhunters." Rosende will make his final "Chicago Fire" appearance in the Season 12 premiere on Wednesday, January 17.
