Marvel's Agents of S.H.I.E.L.D.: Henry Simmons Wants Mack and Yo-Yo to Have Kids

This season of Marvel's Agents of S.H.I.E.L.D. has brought Mack (Henry Simmons) and Yo-Yo (Natalia Cordova-Buckley) closer than ever as they fight for the human race aboard The Lighthouse. It's also given them an opportunity to think about whether they ever want to become parents.

Thanks to their different attempts to foster the young Flint (Coy Stewart) as a fledgling inhuman, it's become obvious that Mack and Yo-Yo would face some challenges raising kids themselves. Yo-Yo is kind of the cool mom, while Mack is the straight-laced dad. After the heartbreak of losing his digital daughter in The Framework last season, it was hard to imagine Mack ever returning to parenthood again, but according to Henry Simmons, it may not be as far-fetched an idea as we think.

"From a narrative point of view, I would like to see that happen," Simmons told TV Guide. "I would love to see the story of them getting together and having a child because it presents so many problems. The child could very well have powers, and then you have that problem with Mack being an individual without powers dealing with a wife that has powers and a kid that has powers as well and trying to navigate through all of that. And then Yo-Yo trying to wrestle with trying to raise a kid normally -- this kid is not normal because it has powers. There's so many different ways it could go. I personally would love to see that story."

"I would love to see Yo-Yo running full speed with a pregnant belly," Cordova-Buckley jokes.

As fun as a pregnancy storyline and then a subsequent baby storyline would be, it's probably not the best time to start tossing out the birth control just yet. First, Mack and Yo-Yo have to get themselves and their team back to the present -- or past...? Ugh, timelines! -- and avoid shattering the world.

After that's all taken care of? Maybe FitzSimmons won't be the only ones hearing wedding bells.

"I don't think it's so much in their future," Cordova-Buckely says. "Even though they're both spiritual people, they both have similar faiths, I don't know. With the mature relationship between them, I don't know if they'd go, 'Let's just have kids. Let's not ever be husband and wife, we're so much more than that by now.' I think maybe they would have a little accident and get pregnant before getting married."

"Now see, this is where I think another thing would come up between Yo-Yo and Mack," Simmons adds. "I think there will be conflict because being a man of God, I think Mack would want to get married. Whereas Yo-Yo would be like, 'Well, I don't think we have to.' I think Mack would want to get married, just to have the relationship covered in the covenant of God. That's what I think, and that would be interesting."
