Tyler Perry's Sistas Season 9 episode 18 ending explained: What did Zac find out about his dad?

Tyler Perry's Sistas has kept BET viewers hooked since its 2019 debut, chronicling the raw ups and downs of four Atlanta friends, Andi, Danni, Sabrina, and Karen, as they tackle careers, love, and life's curveballs in a social media-fueled world. 

Created, written, and directed by Perry, the show blends sharp drama with relatable Black womanhood, drawing from his signature style of quick twists and real-talk moments. Season 9, which premiered in July 2025, dives deeper into grief and growth, airing Wednesdays at 9 p.m. ET on BET.

Episode 18, "Diamonds Are Forever," aired November 19, 2025. Amid the chaos, Zac finds out from his dad’s best friend, Mr Keys, that Zac’s dad left for Atlanta 10 years ago. He then moved to Canada and remarried a South African woman. 

Zac knows that his father was a sperm donor, but what rips him apart is why his father never reached out to him. According to Mr Keys, it could be fear, guilt or simply because Zac’s father didn’t want to have a relationship with him. 

The official synopsis for this season reads -

"Season 9 of Sistas pushes the ladies further to the edge than ever before in their friendships and personal lives. Hardships and huge changes will rattle them, but will it destroy the sisters' circle? These ladies were built to handle the tough things in life, and they'll really need to lean on one another to make it through this season."

Sabrina says that she only has a verbal agreement that she is the sole owner of her embryos. This can cause a legal battle if Sabrina doesn’t agree to Damany’s demand.

Maurice is fed up with the situation, as he has already picked names for the kids, and Sabrina has already paid $20,000 for the IVF.

The core moment of the episodes is at the cafe. Zac meets Mr Keys to learn about his dad, who left him when he was five. Mr Keys said Zac reminds him of “Gold” - the name Zac’s father was called by his friends, as he wore a lot of gold jewellery. This gold, Zac’s father used to steal from the rich folks and he never got caught.

Mr Keys finds Zac and his father similar except for the stealing part. They both are determined, go-getters and hustlers. Mr Keys then revealed how Zac’s dad left Atlanta 10 years ago and moved to Canada, and married a South African woman. Mr Keys yelled at him for not reaching out to Zac and things got heated up. They are not in contact anymore.

Karen meets Fatima and gives her the news on her engagement and that they are moving to Seattle, where Aaron got a job. Fatima says she is happy for Karen and the women share a heartfelt moment. Andi joins the conversation and appreciates the beautiful rings and inquires about wedding plans.

Andi then requested Karen to get the women from Karen’s women's group to pursue a class action lawsuit against Dr Cruise. Andi then throws light on her fight with Danni and how it all started when Andi lied about dating Karen’s doctor, Vaughan.

Meanwhile, Danni meets her therapist and rants to her about how she is on the verge of losing her job, her unemployed boyfriend has moved into her apartment and dirtied the place, while her so-called friend Andi, instead of accountability, thinks Danni is jealous of her. And also her “hair is thinning”.
