NBC's St. Denis Medical aired its finale on Tuesday, April 29, and has already been renewed for a second season. Co-created by Eric Ledgin and Justin Spitzer, the sitcom is "a mockumentary about an underfunded, understaffed Oregon hospital where the dedicated doctors and nurses try their best to treat patients while maintaining their own sanity." St. Denis Medical stars Wendi McLendon-Covey, David Alan Grier, Allison Tolman, Josh Lawson, Kahyun Kim, Mekki Leeper, and Kaliko Kauahi.

Season 1, episode 18 sees the show's ongoing plotline come to a head when Val tells Serena that Matt is in love with her. "This Place is Our Everything" ends with Serena wrapping her head around the new information, while Matt begins to doubt that she will ever return his feelings. In addition to the finale's big reveal, Alex and Joyce both struggle to keep everyone at the hospital happy, but eventually put their foot down and do what they feel is best.

I chatted with Allison Tolman, Wendi Mclendon-Covey, and David Alan Grier about the St. Denis Medical finale's major cliffhanger, Joyce and Alex's dilemmas, and Ron's dynamic with Bruce.

The St. Denis Medical Characters Would Advise Matt & Serena Not To Move Too Fast

"It could blow up in their faces, then you have to keep working together, and it's going to be a horror show."

ScreenRant: What advice do you think your character would give to Matt and Serena after the season 1 finale?

Allison Tolman: I really feel like Alex would be like, "You cannot be with Matt. You will eat Matt alive." [Laughs] She's going to eat him alive. But I think my advice would be to soften her edges a little bit and to just to be a little bit more gentle and a little bit more open, because that's not Serena's strong suit when it comes, especially, to Matt. So I think that would be Alex's advice.

David Alan Grier: Probably Ron would say, "Don't do it." It could blow up in their faces, then you have to keep working together, and it's going to be a horror show. It could be laden with, "Wow, did Ron actually go through this?" Of course, he would never tell, but obviously this has happened.

Wendi McLendon-Covey: I think what Joyce would say, knowing what we know about her useless boyfriend, Sanderson, is, "Keep it light. Don't move in together. Don't be stupid. Keep both of you at arm's length." I think Joyce would say, "Just focus on your careers, really get established, save up a bunch of money, and then if you're still into this after a while and don't lose interest, then pursue it."

But that's Joyce. Joyce is not a romantic. Joyce is all business all the time. [She'd say] "I don't think either of you have the earning potential right now to start a beautiful life. If it's just a crush, just keep it as a crush and keep that magic, because the minute you kiss each other, the crush is broken, the spell is broken, and then you start noticing everybody's ickiness. So don't go there."

Joyce Wants To Be Loved By The St. Denis Medical Staff

"She overpromises because she wants people to love her, but in the end, she can't make good on any of that stuff."

One of my favorite lines in the finale is when Joyce says, "I'm not going to make good on any of the promises that I have made to you." I felt proud of Joyce. I felt vindicated for Joyce. How did you feel?

Wendi McLendon-Covey: That was so much fun to say, and then roll away on my little scooter. I love that Joyce just continues to disappoint. She overpromises because she wants people to love her, but in the end, she can't make good on any of that stuff.

I mean, it's amazing how fast $10 million can disappear and just saying yes to everything. And here's the thing, I believe that everything that was asked of her was necessary, but it's just not going to happen. $10 million doesn't stretch as far as it used to, sadly. [Laughs]

Joyce had such a good idea with the birthing center, which Ron ed. Do you feel like it's become easier for them over the season to compliment one another?

Wendi McLendon-Covey: That's something I hope we can delve into more in season 2. We've kind of alluded to the fact that these two were in their residency together. So they've known each other for decades, and they fight like brother and sister, and they're both jaded.

So I would like to have some flashback scenes of those two in the '90s during their residency and see what happened there. I don't know if we're a show that does flashbacks, but it would be nice to see what went on with those two.

How have you been interpreting that relationship? Because there's definitely some animosity, there's some respect, and it seems like they really do care about each other.

David Alan Grier: Yeah, reluctantly. I mean, we all have those people in our lives who deep, deep, deep, deep down inside, there is some goodness underneath the callous outer shell. That's yet to be explored. I don't really try to come to a lot of conclusions before it's necessary in a character.

So they could go a bunch of ways in of expanding that, giving the audience more information, exactly how our relationship started, and where it is now. I could even envision that Ron was probably going to retire, and then Joyce coaxed him back and said, "No, no, no, we need you here." It's just a thought.

Alex And Tim Are At Peace With Their Recent Life Decision

"They just had to sit down and talk about it, but that time was not in the middle of a gala when they were drunk."

Alex and Tim have decided not to have kids. Do you feel that they are at peace with this decision?

Allison Tolman: I think so. I think that the conversations that happen at home that we never see between the penultimate episode and the final episode—I wish we could be a fly on the wall for them, but I feel like they're really at peace. I think they're a strong couple.

I think that they're really aligned. They just had to sit down and talk about it, but that time was not in the middle of a gala when they were drunk. [Laughs] So that's the lesson from the gala episode—not to try to have those important life conversations in the wrong circumstances.

I feel like Alex has grown so much, and her putting her foot down in the finale really showcased that. How are you hoping she continues to evolve as a character now that you're renewed for season 2?

Allison Tolman: I know. I can't wait to see. I haven't even imagined what is going to happen in season 2. I'm still getting used to the idea that we have a season 2. It's such a blessing to be going back to work again, and for me, it's my first season 2 pickup. I've done some anthologies. I've done some shows that have only had one season, and so I'm still just getting used to the fact that we get to go back to work again. We feel so incredibly lucky.

Grier Believes That Ron Sees Through Bruce's Act

"He thinks he's this super guy, but he's such a fragile man."

What I found really interesting is that it seemed like Joyce and Alex were almost paralleling each other. They were both trying to overpromise themselves to everyone. What do you think the difference was between them?

Wendi McLendon-Covey: I believe that Alex doesn't write checks that her ass can't cash, but Joyce does. I think Alex is firmly rooted in reality, and so anything she's saying, it's coming from a place of truth, and she really just does want to help people.

Joyce is a little different in that she's pushing this entire hospital uphill in front of her. So the things that she promises—Joyce just shouldn't make any promises. She just shouldn't. The follow-through is not there, and the stuff she's promising is just way out of her league. So Joyce should just not promise anything ever.

How do you think Ron feels about Bruce? Sometimes, I wonder if he actually hates him as much as it seems.

David Alan Grier: I mean, when I was a kid, there was this dude who I went to school with. He was from Hawaii. All I asked him about was, "Did you surf? Did you grow up surfing? What is surfing like?" And he just rolled his eyes and he said, "Guys that surf are the gods of the sea."

I was like, "What?" He said, "Because that's how they walked around. They were these great gods of the sea who rode on boards." That's the way Ron looks at Bruce. He sees right through him. He thinks he's this super guy, but he's such a fragile man.
