Which Duggar family member has spent the most time in prison?

The Duggars from "Jill and Jessa: Counting On" are a conservative Christian family who like to keep themselves out of trouble. With the exception of Josh Duggar, who was embroiled in two scandals last year, none of the other Duggar kids has gotten into any serious trouble that would make parents Jim Bob and Michelle shake their heads.

This is why it is surprising to learn that one of the Duggar girls has actually spent a lot of time in prison. "Out of all the Duggars, I would say Jinger's probably the one that's spent the most time in prison," John-David said during the First Look shared by TLC of the episode "Jinger Flips."

But John-David was quick to explain that Jinger's involvement in prison has nothing to do with crime, since she goes there to help share the Gospel to troubled young girls.

"Out of all the ones in the family, Jinger is probably the one that's the most passionate about going down to the juvenile detention centre and just investing in these young girls' lives that are there," he clarified.

Jinger strongly believes that despite the different background she shares with the girls from the juvenile centre, there is still a "common ground" for them to tread on.

At the same time, the episode will also show how Jinger helps in the family's car dealership business. Jinger admitted that she never thought she'd pick up the business, but after attending auctions with her brothers, her curiosity was piqued.

"My brothers are my advisers," she told PEOPLE. "I started watching them, and all my little brothers were making a lot of money. I decided to get in on that."

Jinger's elder brother and sister John-David and Jana are focusing on the family's real estate business, together with younger sibling Joy-Anna, who also earns money through babysitting jobs. On the other hand, Joseph and Josiah are actively involved in prison ministry as well.
