Halstead served as one of Chicago Med‘s most important characters for eight years before he said goodbye to Gaffney Chicago Medical Center at the end of the season 8 finale. He resigned from his position and left Chicago altogether. The last time the audience saw Halstead, he was reuniting with his former love, Dr. Natalie Manning, and her son, Owen, in Seattle.

After more than two seasons, Gehlfuss is back as Halstead in Chicago Med season 11, episode 2, “A Game of Inches.” The hour just so happens to be the show’s 200th episode, making Halstead’s return all the more special. He’s expected to stick around for more episodes following “A Game of Inches,” but it’s unclear how many he’ll appear in before leaving again.

As for why Halstead is in the Windy City in the first place, he comes back to catch a Bears game with Owen. Torrey DeVitto isn’t expected to reprise her role as Manning, meaning her character stays behind in Seattle while her partner and son take the trip to Chicago. Based on Gehlfuss’ interview with TV Insider, Halstead and Owen need time to connect.

The actor teased, “Will has had some struggles figuring out how to bond with Owen.” So, it sounds like Halstead scores tickets to a football game and wants to share the experience with Manning’s son to strengthen his connection with the young boy. However, their plans will likely get ruined as things always go wrong in the One Chicago universe.
