The lab was quite large as a cave. There were two monitors, glazed keyboards inside the monitor, it showed most models of the zombies created by the culprit.

"Oh, so that's the CGI coming out from the hologram!" said Wahid.

He heard muttering sounds of Syedullah and Disco Police. He looked around but he found no one. He crouched and tiptoed. There were echoing sounds coming up. He looked up as he saw both men were hanged upside down.

"Help us Wahid!" shouted Disco Police.

"Help us moshai!" shouted Syedullah.

Wahid shouted back "Oh man! I am in hara-kiri".

"What?" asked both.

"I mean I am in the similar situation as you are, you dope!" shouted Wahid.

Someone put a gun on Wahid's head.  When he looked at the gun-holder, it was a familiar face that he was there all along- Mr. Shah.

"Curse you, detective Wahidur Rahim!" said Mr. Shah.

"Oh, that is so hammy. Ah I am not afraid of death. You want money, huh!" said Wahid with sarcasm.

"I don't need money, I need revenge, sir" said Mr. Shah.

Wahid gave out a wicked laugh. He twisted Mr. Shah's hand that the gun fell into the floor. He smashed Mr. Shah's stomach that made him fell down on the floor. Therefore, Wahid pressed Mr. Shah's chest so hard that blood came out from his mouth. He started the interrogation.

"Who really are you, motherfucking asshole?" asked Wahid.

"I am Durbin Kamal's son, Hassan!" gasped Mr. Shah.

"I knew because, I first suspected you during the event. You were not scared but you were pretending" said Wahid.

Wahid kicked him.

"You knew that all along, but what's the proof?" asked Mr. Shah.

"Proof? Your doctor told me all about you" said Wahid.

"Okay, I'll explain what happened, honest" said Mr. Shah.

Wahid continued to kick him and wiped him out with the belt. Mr. Shah felt painful as that his innocence was coming out of his expression. Therefore, Wahid stopped kicking him because of his expressions.

"My father and I had a really great relationship as if no father and son had. My mom, dad, Ismael's father, your father and Samah's father were partners. There was our garden owned by father. I expected a clean environment until the partners betrayed my father and did not cooperate with him. Therefore, the plane crashed into our garden that spoiled the environment and my family life. I was in a shock of that, that my mom survived and Samah's father as well. I heard they were having an extramarital affair.  Then I killed both of them that led me into the asylum. I escaped and married as tradition. When my wife saw my true colors, I killed her. I put a poison into the chocolate to kill Ismael but it transferred into his mother that she was killed.I wanted to use you fucker but your perverted nature slaps my mind. I created the zombies with the projectors not only for revenge but also to save environment because environment is a need of life" said Mr. Shah.

After the showdown was over Wahid shot Hassan's (Mr. Shah's) leg.

Wahid revealed "at first, I went to the plane and analyzed the projector wires. Your gases are actually drugs to make people hallucinate about zombies. As you are good in Physics and Computer Science, I have downloaded a software where I realized that you modelled zombies from there. As I know that you had an elder brother who looked like you. You drove him mad because of your true colors that gives out a perfect collision. How do I know that? I met your brother again and talked to him about the past. He told me such things that I wasn't prepared to hear for. Nafisa also told me about you giving her a shock therapy while I went to the hospital. The documents were also against you as well. You are chemically imbalanced but the society needs you but you are the shame. God may also not forgive you. Everyone has a mental illness except 10 percent who are deranged. You are one of the ten percent".

"Good going, sir" said Mr. Shah.

"You fucking of a psycho of a demon of a what? Something more profane. Wanna have money? There's no money but mental asylum for you" said Wahid.

 "Right, Wahid" said a familiar voice.

"Samah?" exclaimed Wahid.

"Yes, darling. I am that someone else that Professor Abir mentioned you about" said Samah showing her sultry face. At the back, it was Abir and his wife, Rubina with their daughter Abira and his secretary Ramzan.

"I think I could reveal you things that you don't know Wahid" said Samah.
