Jarvis is accused of splashing Michael with rubbing alcohol, and Mendez is accused of using a lighter to set the boy on fire.
Despite his gains, physically and emotionally Michael is far from fully healed.
He has nightmares, which he doesn't remember when he wakes up.
"I know about them. He screams in the middle of the night. He sleeps through them," Valerie Brewer said. "It helps me a little to know he doesn't remember any of it."
Brewer urged people not to forget about what happened to her son and to other young victims of violence.
Two younger boys who were present were not charged because police believed they were bystanders.
The Brewer family said in a statement that it wished to thank "all who donated time, care, well wishes or funds for Mikey's recovery."
