The latest trailer for ‘Jill & Jessa: Counting On’ season two was recently unveiled, promising more than a few major moments for Duggar sisters Jill, Jessa and Jinger, who announced her engagement to ex-soccer player Jeremy Vuolo last month.

In July, People Magazine announced that Jinger and Jeremy were engaged after one month of courtship. After accepting the former professional athlete’s proposal, the Christian couple shared an official statement, saying they were "so excited to take this next step in spending our lives together" and expressed their gratitude to family members, friends and fans who sent congratulatory messages.

There have also been speculations that TLC will be taking away the ‘Jill & Jessa’ in the title and will instead settle for ‘Counting On’ as a means of re-introducing the show with the other younger brothers and sisters, such as Jinger and Jana. The official trailer for the second season also teases such idea because of its use of the hashtag #CountingOn.

However, such new concept has some fans questioning as to which Duggar siblings will take the spotlight in the new season. Aside from Jinger getting engaged to Jeremy, there have also been questions about the appearance of eldest brother Josh and his wife Anna in future episodes. Other viewers are also concerned whether Jana, who is often named as the Cinderella Duggar by her fans, will also have a special moment in the second season.

"Joy, Jedidiah, and Jeremiah are reaching a milestone with high school graduation rapidly approaching while John David, Joseph, and Josiah could be seeking new relationships," the synopsis states. Jana was not featured in the ‘Counting On’ season two promo or description.

The ‘Counting On’ season two begins with "Jinger and Jeremy's courtship bliss". With their engagement and acceptance of the Duggar family’s rules, it is expected that another Duggar marriage will be carried out soon.

"Sweet little Jinger is now grown up and engaged! We are so happy for them both. Above all, we are so grateful for their love and commitment to Christ. We are so excited about another Duggar wedding! We know that wonderful days are ahead for Jinger and Jeremy and we are looking forward to every moment! Our entire family rejoices," the Duggar parents stated in a post on their official website.

Meawhile, after a year of doing missionary work, Jill and husband Derick will return to Arkansas. Aside from raising baby Israel, their one and half-year-old son, the Dillard couple is planning to have a second baby and expand their family.

As to whether Jessa and husband Ben Seewald plan to bear a sibling for baby Spurgeon Elliott, the pair’s plans for adoption will be discussed in the upcoming season.

All in all, the new episodes will draw attention to the grown-up children of the ‘19 Kids and Counting’ couple, Jim Bob and Michelle, and the ways with which they go through relationships, parenting struggles and other exciting adventures.

Comprised of 10 episodes, ‘Counting On’ season two will make its premiere on August 23, Tuesday, at 8/7c in the U.S. on TLC.
