Gambi cautiously walked in and immediately came to Jefferson's aide as he laid on the floor unconscious. Later on, he was watching the news just as Jefferson was waking up. He told Jefferson that he thought he was done being Black Lightning as he pointed towards the news report. Jefferson thanked him for patching up his wound. Gambi told him how Freeland needed him and asked what he would do next. However, Jefferson told him that he's not becoming Black Lightning again as Jenifer is safe. Gambi reminded Jefferson that he became Black Lightning to give the community hope and give the evil something to be afraid of. He went on to say how the evil has plagued not only the city but also the entire world since he stopped being Black Lightning. Jefferson argued that he originally became Black Lightning to kill Tobias as revenge for murdering his father, Alvin Pierce. Jefferson told him how the violence will never end and that he always came out to be the loser. He went on about him and Lynn on the verge reconciling and Black Lightning will not jeopardize it. Gambi said he understood how important repairing his relationship with Lynn is; however, Gambi told him that Jefferson knew the day would come, he would have to come out of retirement.
The next day, Gambi was working in his shop until Jefferson came in. He informed Gambi that Jennifer and Anissa were kidnapped by The One Hundred. Gambi told Jefferson to go downstairs as he closed his shop to prevent people from coming in. Downstairs, he showed Jefferson the designs to his new suit. 
In LaWanda: The Book of Hope, Gambi was listening to Jefferson rant about Lala and Will not being arrested for kidnapping his daughter. Gambi told Jefferson how understood him, but if he had died at the Seahorse Motel, then the city would not have any hope to rise up and fight against the 100. Jefferson told him that he wasn't protecting the city, but only wanted to protect his daughters. Therefore, Gambi suggested Jefferson get back into his suit and he would hack the Freeland Police Department, so he could find Will. Once Will was found, Will would turn against Lala and lead them to him. Gambi told Jefferson that if Lala is arrested, they would find out who's the leader of the 100. Jefferson told him that once they get Lala, he will stop being Black Lightning for good.
The morning after LaWanda's murder, Gambi called Jefferson to let him know that he found Will's body along with his phone. Jefferson said that Lala is getting desperate and informed him of LaWanda's murder. Gambi reassured Jefferson that they would find Lala. He hung up and left the alley. Later on, he contacted Jefferson to inform him that he'd found Lala's location.
