This fall on BET and BET Plus is packed with drama, as "Zatima" returns and "Tyler Perry’s Sistas" premieres on October 16. The biggest mystery? Who killed Gary. There’s a long list of people with motives, and Zac might be on that list, especially after Gary had his bodyguard rough him up over Fatima. But let’s be honest, Zac probably didn’t do it. Here are five reasons why.

He Has a New Lease on Life
Zac has a dark past, but he’s been working hard to turn things around. Therapy and his relationship with Fatima have helped him grow, and he’s committed to staying on the right path.

He’s a Hot Head, Not a Murderer
Sure, Zac’s temper is no secret, and he’s not one to back down from a fight. But taking someone’s life is another story. Even when his loved ones are hurt, Zac knows he has too much to lose.

He’s Grieving
Zac is dealing with the death of his mother and the stress of his brother’s addiction. His emotional and mental state is fragile, and murder is the last thing on his mind.

He’s Got Bigger Problems
His business is falling apart, and his financial issues are piling up. With the weight of burying his mother and supporting his family, Zac has enough to worry about without adding murder to the mix.

He’s Focused on His Growing Family
Zac just gained custody of a son he didn’t know about, has twins on the way with Karen, and Fatima is pregnant. With so much at stake, he’s focused on building the family he’s always wanted—not throwing it all away.
