The West family has seen their fair share of ups and downs throughout the duration of The Flash . Long lost sons, prophesized deaths, and manipulative super villains tend to complicate things.

And Joe West and his girlfriend Cecile Horton were thrown yet another curveball in Season Four, when Cecile revealed to the Central City detective that she was pregnant.

Actor Jesse L. Martin spoke with ComicBook.com during a recent set visit about his character's reaction and how it will change Joe moving forward.

"He's really happy to be having a baby with Cecil but both of them are scared to death about being older and dealing with a little baby," Martin said. "We both have full-time careers and of course I'm fighting crime with Team Flash so baby's going to put a monkey wrench in the program but I guess it's going to be a good monkey wrench. And who knows what kind of baby is going to show up in Central City, right?"

Previously in the series, Joe and his daughter Iris had to deal with the addition of Wally, whom they never knew about until he came into their lives. Now, Joe is having another child and Iris is getting a very, very young sibling — and she's pretty excited about it, according to Candice Patton.

"I think she's super excited and happy for Joe," Patton said. "It's been a long time coming for him to have a relationship on the show. They're definitely older and going to have a newborn and that's a weird, strange thing. We'll delve into more of that as the season goes on. I think Iris is really excited to be a big sister. Maybe it will inspire her to want to have children sooner rather than later too."

With Iris and Barry set to tie the knot, are wedding bells in the future for Joe and Cecile?

"That's not in the cards yet. But I'm assuming at some point we'll get married? I mean, we're about to have a baby so it's kind of like being married I guess," Martin said.
