For those of us who have been watching Little People, Big World since the Roloffs first arrived on the scene in the mid-2000s, you may have noticed there have been a few, uh, "casting changes." While much of the show focuses on life-after-divorce for Amy and Matt, there are also entire storylines dedicated to Zach and Jeremy as they navigate the new worlds of marriage and parenthood! But noticeably absent are the twin's younger siblings, Molly and Jacob.

Jacob has been candid about why he no longer does the show — while Molly's absence has been a lot more mysterious! So what do we know about Molly? Well, for starters, she's married!

Molly's now-husband, Joel Silvius, popped the question just days before Christmas in 2016, and it was clear from social media — and the most recent season of Little People, Big World — that the entire family was absolutely elated for Molly and her husband-to-be, who exchanged vows in August.

According to LinkedIn, the 24-year-old studied accounting in Spokane, WA — far from her family's farm in Oregon — and decided to settle in Spokane with her new hubby. Unlike Jacob, Molly does make some (albeit infrequent) appearances on the show.

Recently, Jacob explained why he made the decision to stop filming with TLC, even though he is currently filming his own web series (which means that he doesn't have a problem with sharing his life with millions of strangers). "I saw a comment on something and somebody was asking why I don't just do a show since I'm filming myself right now," Jacob said. "There's two ways to do the filming thing — one way is through the show, maybe and the other way is through myself and vlogs. It's just more free doing it myself, I can do anything, I can say anything, I can talk about anything — I can show whatever I want."

The 21-year-old compared filming with TLC vs. filming by himself to living in a city with air pollution vs. living in the countryside. He also said that he doesn't want to be recognized as Jacob from Little People, Big World because he would rather be recognized for one of his own projects — or he would just prefer not to be recognized in public at all.

"I don't want people to think that I'm living in a resentful sort of way towards the show — I've moved on from it," he explained. "It's just a natural progression of leaving the place you came from, moving on away from home, traveling away from home. Just getting away."

Well, to each their own! But we hope we get to see Molly on the show again tonight when LPBW airs its new season.

Little People, Big World premieres tonight at 9 p.m. EST on TLC.
