'The Walking Dead' star almost thought she was going to have her baby while they were making the series finale

• Eleanor Matsuura was far along in her second pregnancy while filming the final season of "TWD."
• Matsuura told Insider there was a moment when she thought she may have her child on set.

"The Walking Dead" star Eleanor Matsuura was a little nervous when filming for the show's final episode started to run long while she was far along in her pregnancy with her second child.

"It started to go and go — and things get pushed because it's a job and it gets busy, you know, things get chaotic. All the meanwhile, my belly's getting bigger and bigger and bigger," Matsuura told Insider on the series finale red carpet.

"There was a point where I was like, 'Am I gonna have to ask Norman Reedus to deliver this baby? Am I having my baby surrounded by walkers?' I don't want that to happen," Matsuura added.

It didn't come to that.

Matsuura, who played Yumiko on the show since season nine, shared a photo of her child with her husband, Trevor White, a week after their birth on Instagram in May.

"The Walking Dead" wrapped filming on the last day of March. Yumiko survived the entire series.

While discussing the finale days earlier over Zoom, executive producer and finale director Greg Nicotero told Insider the production team worked to make sure Matsuura would be accommodated.

"Eleanor was like, 'Guys, you gotta be done with me on this date because it's gonna be weird if all of a sudden there's one day I'm pregnant and the next day I'm not," Nicotero said.

"Thankfully we finished just in time and then I went and had the baby," Matsuura said, adding, "There are a couple of shots, I think, in this episode where you can definitely see a pregnancy."

Near the show's very end, if you look closely at Yumiko as she's picnicking with her girlfriend, Magna (Nadia Hilker), Connie (Lauren Ridloff), and Kelly (Angel Theory), you can notice her baby bump.

"Everyone kept asking me, "Do you think they'll be able to write it in the show?" Matsuura said. "I was like, 'I don't think so, unless they're dealing with an immaculate conception.'"

When we pointed out that Yumiko's brother, Tomi, is a doctor in the Commonwealth community and that maybe in vitro fertilization wasn't out of the question in the future of the apocalypse, Matsuura said it was a possibility she didn't consider until we brought it up.

"He's a doctor. He could've slipped me this little IVF treatment," Matsuura said. "You're right. I never thought about that."

It's possible that could've been the show's intention. When Yumiko is seen on-screen with Magna, Connie, and Kelly, all of them but Yumiko cheer with glasses and a bottle of wine.

Of her time on "TWD," Matsuura said, "It's truly changed my life. I don't know if another job I'll ever have will compare to this experience."

When asked if there's a chance we could see Yumiko again on a "TWD" spin-off since she survived the series, Matsuura said, "Never say never."

"There's nothing in the works right now," Matsuura added. "But I really don't see why not. Yumiko's one of those characters that could easily fit into any of those spin-offs. So, who knows?"

Three more "TWD" spin-offs have been announced so far, including a Daryl Dixon series, a Maggie and Negan spin-off called "Dead City," which recently wrapped filming on its first season, and a Rick and Michonne series.
