This post contains spoilers from Wednesday’s season 8 finale ofChicago Med.

Another doctor has left the E.D.

On Wednesday night’s season 8 finale ofChicago Med, Dr. Will Halstead (Nick Gehlfuss) decided he’d had enough, and, at the same time, may have wound up with everything he’d ever wanted.

“What are we going to do?” she mused, calling him “a constant source of irritation and a constant source of inspiration.”

Just one day before audiences would learn Halstead’s fate, PEOPLE caught up with Gehlfuss, 38, about career-making turn on the show and his departure. But first, since he isn’t active on social media, he wished to address the show’s passionate fans directly here:

PEOPLE: It’s mere hours before fans will see Halstead’s departure. How are you feeling about it?

NICK GEHLFUSS:I’m feeling a lot of things right now. I don’t even know where to start, but overall good. I’m very much thinking about the fans. But I don’t think they’ll be ready, and I do think the writers have done a fantastic job with misdirecting Will’s exit with Maggie’s interviews.

What went into the decision to move on fromChicago Med?

It was a difficult decision, but I felt I had taken Dr. Halstead as far as I could go with him. I really value my time on the show and I’m so grateful for it. I’ve learned a hell of a lot and it’s changed my life for the better. The hardest part is leaving the vast talented group of good people. I’m so proud of the work we accomplished.

What do you remember most from when you first got this part?

In November of 2018, I received a phone call for this job, and if you would’ve told me I would’ve filmed over 200 episodes of television, I would have not believed you. Until that point, I had done six episodes at most for one gig. The finale is my 163rdMedepisode, and I have done 21Chicago Fires and 18P.D.for a total of 202 One Chicago episodes.

Dick [Wolf]took a chance on me, and at the beginning, I was not a serious regular. And really, it’s a prime example of making sure an actor knocks every audition out of the park because I had an audition forChicago P.D.and they said they loved my audition and would love to have given me the role, but I looked too much like someone else on the show. So whenChicago Medwas starting off and they wanted to create this brother role to Jay Halstead, Jonathan Strauss, the casting director, reminded them, “Hey, remember when you said this guy looked too much like this guy? Well, now you want someone that looks like this guy. So what about this guy?” It’s a great example for every actor who doesn’t already understand this, that every audition counts, even if you don’t get the role. It’s not necessarily about getting the role every time.

Had you ever considered living in Chicago before this?

Chicago wasn’t even on my radar and now it’s my home.

What is something that Will Halstead taught you that you’ve applied to your life?

Well, he may have not fully understood this lesson because he sometimes let his personal life or personal wishes for patients get in the way, but you never want to let your personal stuff interfere with your work.

What was your reaction when you first read how Will’s departure was written in?

I thought they balanced it very well. Will was making a choice beyond just love for the hospital. He was losing faith in the hospital because it had gone for-profit. That really goes against everything Will stands for, especially as it pertains to his protection over his patients. But at the same time, I think Will was always seeking elements of Natalie in every relationship that followed their breakup because he never got over her. So the relationship for Will and Natalie comes full circle and it was a beautiful moment with Natalie. And it’s not just Dr. Manning that shows up, it’s Owen. I really always admired that about Will’s character, that he was willing and open to being a stepfather. So there’s this family at the end, not just a couple, that’s really reunited.

How was working with Torrey DeVitto again?

It was so great to see her, and we fell right back into our work rhythm as if we didn’t have any time off. It was really just a terrific moment and one that I hope brings some closure to fans. I think the writers did a fantastic job with that.

Were there a lot of tears on your last day?

Of course.My wifevisited for the last day to see the final scene, and when she arrived, I think it was an AD who said, “Have you seen Nick?” She said, “No.” And this person said, “He’s been crying all morning. He’s a wreck.” And it was true. These are eight-year relationships that I have with the crew that — we don’t use the word lightly, and that’s the only word for it — is family.

Anything else you’re really going to miss?

It’s been a wonderful experience and one that I will never forget. I mean, we are a success story that will go down in history in television. I will never forget the amount of mental health stories we’ve been telling and thatChicago Medwill continue to tell. It’s just so important. Sometimes entertainment is the one that brings about cultural shifts, and I think we’ve been erasing stigma around it for the past eight years. And there’s no one better to be at the head of that than Oliver Platt because I know how much he cares about it all and wants to get it right. So yeah, Dick not only did he put all these shows together, but he also brought a psychiatrist into a medical drama and felt that audiences were ready to start hearing about these types of stories.

What’s next for you?

A lot of One Chicago-ers who have left come back, whether to direct or otherwise. Is that something you would consider?

Yes, actually Dick, the producers and I agreed to end the storyline to preserve the ability to bring Halstead back if the opportunity presents itself.
