But it might be different kind of fireworks than Erica was planning. Because Mitch and Tina have a sit-down and he offers to work on her upcoming solo project with her. Tina's full reaction wasn't shown but she was definitely all smiles at Mitch's offer.

Still, it was when Erica revealed she got an offer to perform elsewhere on the same day as Tina's wedding.

Tina made it clear it was mandatory for Erica to be at the ceremony.

"You're gonna call them back and tell them you ain't available. You're gonna lose a sister over your career."

On the wedding day, Tina is preparing to walk down the aisle and Erica is nowhere to be found. It was an extremely important day for Tina as it was her second wedding to her husband Teddy. Last year the couple experienced lots of turmoil as he confessed that he had several affairs. After months of drama, Tina forgave him and he proposed once again. This season has already shown their progression.

Mary Mary airs Thursdays at 10/9c on WeTV.
