Sal & Gabi Fix the Universe

After looking over the paper an alternative version of himself wrote, Gustavo has succeeded in his research after a test run proved to be successful. After the experiment, it asks Sal if it is alive, which he says yes, it is. Later that night, Sal asks it if it is repairing the universe, which it is not. After saying it’s work might be hurting him, it apologizes. When he introduces it to the Entropy-sweeper, it reveals that the Entropy-sweeper tried to hack it to become a class-nine AI, which it can as code sharing is illegal and says the Entropy-sweeper must turn itself into a class-nine. After a brief argument, Sal convinces it to tutor the Entropy-sweeper and names it Brana. However soon after Gustavo reveals that he has been listening in on the conversation.

Later that day when Sal Brings an alternate universe Gabi Real home, it sends her to another universe. It and the Entropy-sweeper congratulate themselves as Sal says not to do it again. He becomes shocked when they tell him the other Gabi was right about about the dangers of closing off the universe. When they say they will lie to his father, but he encourages them to tell the truth just as Gustavo returns home. As Sal hides in it, the two AIs say he is dead. It spends the rest of the day blocking the other Gabi from entering the universe.
