The season will kick off with a major boat crash.
Ripley knows a thing or two about walking away.
After joiningChicago Medin season 9, Dr. Mitch Ripley (Luke Mitchell) quickly became a fan-favorite character.

And that was after he had done some damage to his relationship with Dr. Charles (Oliver Platt).

Is the medical jargon as difficult as I think it is?
LUKE MITCHELL:Absolutely.
And they send you home with a little toolkit to practice and get the feel for it.
You got to look like you know what you’re doing, right?
I definitely feel more settled this season, which is a really lovely feeling.
But every scene is different and every episode is different, and there are new challenges around the corner.
How much did you know about Ripley going in?
What was your reaction when you read the season 9 finale and saw Ripley walk away?
I need to know.
I don’t think I did, but I could have.
Is he capable of doing this thing?
Where do we pick up in season 10?
There’s a little time jump.
What kind of head space would you say Ripley’s in when we find him?
Not a great one.
[Laughs] Some time has passed.
There’s more than a bit of tension between him and Asher [Jessy Schram].
They’re not in their best place.
I’m not sure they’re communicating as effectively as they could be.
But it’s the premiere episode, and there’s a mass casualty incident.
So it’s not just dwelling on what happened at the end of last season.
That’s the undercurrent for sure.
And we will be delving in there, but the almost immediate focus is there’s a boat crash.
So we are now told that our intake’s basically going to be doubling, and it’s chaos.
So perhaps we can get into the Asher situation after the premiere?
I think Hannah’s going to be a big part of his walls coming down one way or another.
So yeah, I mean, it’s going to be really interesting to see how their dynamic unfolds.
Do you feel like you’re learning more about his backstory?
Do you think the audience is going to learn more about his backstory this season?
Moving forward, we are going to see a less well-kept Ripley.
And so the edges are going to start to fray.
Chicago Medpremieres Wednesday, Sept. 25, on NBC.
