As the team made their way to Bangui, Jesse's advanced drone found a facility in the outskirts of the city. When they reached there, they found an old warehouse. Entering it, they were shocked as they saw all kinds of serums and also poisons. They noticed the body of a lab chief Cyrus Dacko in the corner slashed by some sort of a blade. They found some files which helped them in suspecting lab intern Maxwell Longbottom, who told that the victim's home was nearby. In the victim's home, they found a gun, a katana and a lab badge. The gun turned out to be of Imogen Dacko the victim's mother, who told she needed it after a thief broke into the house once. The lab badge turned out to be Akshay Gupta's who they had met during the opening party, who explained he came to the warehouse to collect materials for his invention. The katana revealed that the killer read the book In Search of Lost Time. The victim's body revealed that the killer knew how to make tie-knots. After that, they got a message from his intern.

The intern told them that there was strange noices from a corner of the lab. Opening it, revealed a secret chamber. They found a Lab Set and a Packet Of Rice there. The lab set was revealed to be belonging to SCROB 2.0, a robot created by the victim. The packet of rice revealed that the killer had a pet mouse. They went to his house in search of clues where they found a CCTV Camera, a set of remotes and watch. The camera revealed that Cyrus had argued with his mother, hours before the murder, which his mother said was her biggest regret. It was also revealed that remotes were given to him by Akshay who told him to configure a model remote from that and the watch was of Astrid Oroko, a lab technician. She told them that the victim was her idol and she would never hurt her. After that, SCROB tried to break into the team's building.

It was revealed that the victim was trying to dismantle SCROB 2.0 to make SCROB 3.0. The detectives also checked the file section of the secret corner again where they found a message and a scarlet brooch.
