The new season of WeTV's Mary Mary is in full swing and while fans saw a lighter and more joyful side of Tina Campbell, a new trailer reveals she was at risk of sinking back into her old ways.

The explosive teaser opens with Campbell, who stars in the show with her sister and Mary Mary counterpart Erica Campbell, revealing that she is almost at her breaking point. This is kind of surprising because she was all smiles at the end of Thursday night's episode as she and her husband, Teddy, enjoyed a date night.

The couple has definitely come a long way after he confessed last season that he cheated on her with multiple women. But it looks like he has more news for her that threatens to set Tina back once again.

While the actual announcement doesn't show in the clip, Tina's reaction does.

She tells Teddy, "This is a whole lot."

She goes on to call Erica and ask, "Have you heard this crap?"

Erica also gives a hint at how drastic the news is.

She says, "Lies like this could take my sister back to the dark side."

This is certainly a turn of events from Tina's happy ways in the fourth season opener. She made it clear that she is working on being a more joyful person since she and Teddy are working on fixing their marriage. But Erica wasn't too hopeful as she continued to question just how long the new Tina would stick around.

Check out the trailer below.
