Sarah Ramos‘ debut as Dr. Caitlin Lenox in the Chicago Med Season 10 premiere certainly rubbed some people the wrong way; in her first episode, she shocked Dr. Dean Archer (Steven Weber) by revealing she’s his co-chief in the Ed and fired a doctor! The tension between the two bosses has continued since, and it doesn’t sound like it’s going to let up anytime soon, with their different approaches to doing the job. Below, Ramos reveals what’s ahead for Lenox, including a backstory that might have you thinking differently about her.

Sarah Ramos: Archer is still huffing and puffing his way through the Ed, not really accepting or respecting his co-chief. So there’s more that Lenox has to respond to.
