Two members of the expansive Duggar clan — Jill Dillard and Jessa Seewald — are returning to television this December for a three-part TLC special titled Jill and Jessa: Counting On, which follows how they’ve been dealing with life after news broke last spring that their older brother, Josh, had molested them — along with three other underage girls — when he was a teen.

The special will follow Dillard’s move to Central America to do missionary work as well as Seewald’s pregnancy. “There’s still a lot of exciting milestones,” Seewald says in a new promo. “We will come out of this fire,” Dillard adds.

The 90-minute premiere will air Dec. 13 at 8 p.m. ET on TLC, while the other two will air Dec. 20 and 27 at 9 p.m. ET. Watch the latest promo below.
