First thing was first. Donquisha had to help her man.
And after some thought, she said "I wish Tyrone wadn't arrested and was right here wit me."
The stone glowed, granting her wish. And in the blink of an eye, Tyrone was standing in the middle of the room, un-handcuffed.
"Who da hell are you?" Tyrone asked. Then his eyes went wide when he saw the stone in the woman's hand. "How you get dat? It was in mah safe."
"Tyrone, baby. Why you flippin' out like dis? You know who I is. I's your girlfriend, your bitch. Donquisha Chase. 'Member?"
Unfortunately, since Tyrone wasn't around her when she made the wish, he didn't hear it, so his memories were changed to fit the new reality. And in the new reality (as he saw it), he was never arrested, so he never used his power to change Danielle Chase into Donquisha. But Donquisha still had to exist regardless, since she was basically created via the wishing stone.
"I don't know you. And ah ain't got no girlfriend," Tyrone said. Yet, he added in his head. He still hadn't used his new power, as far as he knew.
