In the video, a tearful Anna explains, "It was heartbreaking to hear what had happened."
But even more moving is her silence, as she seems to reflect over what had happened to her family, before adding a somber, "Ya."
Jill revealed that when she heard the news of Josh's affairs and his addiction to pornography, her first thoughts were just for her sister-in-law Anna.
"I cried a lot of tears," Jessa said. "Somebody who you love, how could this happen?"
But despite the turmoil the family has endured, they make it clear in the sneak peek that the three-part special will be focused on their family moving on.
Josh remains in rehab while Jessa and Jill are focusing on their new little families with their husbands Ben Seewald and Derick Dillard, respectively.
"We're gettin' through," Jessa says, before we get a glimpse at the sisters preparing for the arrival of Jessa's first baby. The little guy, named Spurgeon, was born just two weeks ago.
And Jill agreed, "We will come out of this fire."
Check out the full sneak peek of the TLC special below.
Of course, Jill & Jessa: Counting On has already brought its fair share of controversy all on its own. There are reports that hundreds of advertisers have refused to have their products marketed during the series as a boycott against what the Duggars stand for. And social media campaigns against the show have gained a lot of successful traction.
