Da: Which reminds us, the first couple of episodes of your latest show, “Station 19,” have started airing. in a nutshell, what is the series about? Can you also tell us a bit about your role? Jh:

We follow a group of first responders—fire, Search and rescue, eMts—at work and their personal lives. in Seattle, teams work 24-hour shifts, so they live and work together. they are like a dysfunctional family. there will be aspirational friendships, people at odds with one another, people who are secretly sleeping together. i play travis, funny, sarcastic, but by the book.

Wearing the turnouts, the helmet, the oxygen tank, the axe, the chainsaw, and having the hood, gloves and mask on was ... challenging. We were constantly drinking water because we would sweat out more than we were putting in.

Both shows are physically very demanding. Both shows are about people acting in a team that faces life and death. And both shows have amazing tech advisors. Men and women that have truly done the job at the highest level.
