Krista Vernoff offered updates on where the characters were at in Season 6 of “Station 19” and what they were dealing with, and it would seem that Jack Gibson is not doing very well as the latest batch of episodes kicks things off (via TV Insider). Jack is struggling badly after finding out that, while he was forced to live his young life in the foster care system, many of his siblings were kept by his birth parents, allowing them to live more stable lives.
Though the character is indeed returning for Season 6 of “Station 19”, the showrunner explained that he would not be the same. “When we find him, he’s [no longer] a firefighter, and struggling with this emotional fallout,” Vernoff explained. While there are several other characters in the series facing their own demons as the show returns, the threat of a tornado will force many of them to unite in order to stave off the destruction and help the victims of the natural disaster. How the crew of “Station 19” will face this crisis without Jack to help them out, though, remains to be seen.
