Fans were dying to find out if Robyn was pregnant on the Sister Wives tell-all episode, but some unexplained tension on the set left everyone with more questions than answers.

Robyn's Pregnancy Confirmed?

Things appeared to be going well during the interview between Kody Brown and his four wives and Tamron Hall, but as the topic moved more towards the idea of Robyn potentially being pregnant with baby number 18, Christine appeared to grow uncomfortable-and even walked off the set. Fans then learned that Robyn refused to answer any more questions about the topic-leaving them without the answer they wanted most.

Now, with fans clamoring for more information as to what caused Christine to walk away, Kody's third wife maintains she wasn't upset over the talk that Robyn wants to have another baby.

Brown Family Proves Commitment & Loyalty To One Another?

"I just had to walk off the set. It's true. I had to wrap my mind around an issue. Sometimes it takes me a while. #Sisterwives," she tweeted during the July 27 reunion episode.

After fans pressed her for more information about what was bothering her, Christine was vague, but maintained she wasn't upset over Robyn wanting a baby.

"Why did I walk off the set? It's complicated, but it's not because of Robyn wanting a baby. Honestly, it was childish and I shouldn't have," she wrote.

However, the tension very well could still be tied to Robyn and a possible pregnancy-as Kody continues to potentially be dropping hints that he and his fourth wife are expecting their second bundle of joy (and the family's 18th child overall) together.

"Nothing to say except: We are a great show for a First Response pregnancy test add! Uh...right??" he tweeted during the broadcast.

The tweet about a pregnancy test comes just one week after he tweeted to Robyn during the season finale episode about possibly having another kid together.

"Super Sol! Thanks @LuvgvsUwngs A cute little boy! Only the 3rd child shy of 17...Should we have another?" he wrote at the time.

Fans were anxious to learn if baby number 18 was on the way, as the family's expansion has been a focus for years. Initially, a new baby had seemed like something that could come between Kody and his first wife, Meri, after she expressed back in season three that she didn't know for sure if she wanted another baby, since her infertility would require Robyn to act as her surrogate.

Considering Meri expressed her feelings of dissatisfaction with the family all during this current season--including admitting to having "first wife feelings" when the family went to visit with another polygamist family and deciding to go back to school and abandon the business, fans were expecting a double announcement that Robyn could be pregnant and Meri could be leaving-but neither kind of announcement was made, and Christine walking off the set was the only tense moment that occurred.

If news of a pregnancy is eventually confirmed, the strange behavior Christine exhibited could then be the hint fans have hoped for. For now, however, they will need to wait and see if their favorite family practicing plural marriage will continue to grow.

If another child is born, it would join: Logan (Kody's son with Janelle), Aspyn (Kody's daughter with Christine), Mariah (Kody's daughter with Meri), Madison (Kody's daughter with Janelle), Mykelti (Kody's daughter with Christine), Hunter (Kody's son with Janelle), Garrison (Kody's son with Janelle), Paedon (Kody's son with Christine), Dayton (Robyn's son from a previous marriage), Gabriel (Kody's son with Janelle), Gwendlyn (Kody's daughter with Christine), Aurora (Robyn's daughter from a previous marriage), Ysabel (Kody's daughter with Christine), Breanna (Robyn's daughter from a previous marriage), Savanah (Kody's daughter with Janelle), Truly (Kody's daughter with Christine) and Solomon (Kody's son with Robyn).
