A week later, David returned to the gang hideout. Hope and Liam had the information ready. "It turns out that you were right, David. But it's not just one mole, there are moles. Three of them, to be precise," Liam informed.

"One is a brute, the second is a stalker and the last is actually a leader." David understood Hope's terminology. Gang brutes were usually men with stocky builds, and were well-trained. They were capable of blocking many attacks, and they could even block some Assassin attacks. Gang stalkers were members who wore civilian clothing and could blend in with crowds and hide in hiding spots rather well. They were all capable of assassinating their targets.

Gang leaders could do what both the brutes and stalkers were able to do. But they were the most well trained men in Hope's gang, and they were not defeated easily.

David found the brute walking on the street. He pulled out his Queen Anne pistol and fired a warning shot. The civilians started fleeing in all directions. David scanned the crowd and saw two men heading towards him. Looking at their faces carefully, David recognised the two men as the other two traitors. David quickly switched his pistol with his basket-hilted sword.

After a few seconds of exchanging blows, the gang stalker produced a smoke bomb and threw it on the ground. The leader and the stalker ran away as the smoke filled the air. David began chasing after them.

The brute attempted to stop David in his tracks. The brute pulled out his axe and took a vicious swing at David. David managed to parry the attack, but he knew he could not hold for much longer due to the axe's heaviness. At the last possible moment, David softened his knees and got into a crouch. The axe flew across David's head, just a centimetre from his hood. David's fist flew towards the brute's jaw as he got up from his crouch. His fist made contact with the brute's jaw and the brute staggered backwards. David thrust his sword into the brute's chest.

David sheathed his sword and began climbing the nearest building. He saw the stalker and leader making their escape through the rooftops. David quickly gave chase.

Not long after, the stalker and leader went their separate ways. David decided to chase after the stalker, who was still on the rooftops. The leader had leaped off the building and blended into the crowd.

David caught up with the gang stalker a few minutes later. The stalker drew a long and thin knife and attacked David. David moved away from the attack, released his Hidden Blade and stabbed the stalker in the back. David lay the gang stalker's body on the roof and reported back to the gang hideout.

"The leader's still alive? Damn it!" Liam remarked. "Luckily you killed the other two traitors. But with the leader still alive, Hope is in danger." David nodded. "I understand. I will bring Hope to a safe place until the leader is killed."

"But, your contributions have been great thus far. Achilles wishes to reinstate your status as an Assassin. I support his decision. Are you agreeable with that?" Liam asked. David looked at Hope and she advised. "You should accept it, David. Being an Assassin allows you to do certain things an ex-Assassin can't."

David agreed in the end. Hope and Liam re-welcomed David into the Assassin Order by giving him a second Hidden Blade. "Perhaps you want to discard your old one, or you may want to dual-wield your Hidden Blade?"

He accepted the Hidden Blade and equipped it on his other hand. "I guess I should dual-wield it. Two is better than one, is it not?"

As David made his way back to his apartment, he was ambushed by a gang leader. The gang leader, whose face was mostly hidden by a brown hood, produced a short sword and held David at knifepoint. David caught a glimpse of the leader's face and recognised him as the betraying gang leader.

"You think you can live after killing my two comrades? You are wrong," the gang leader snarled. David released one of his Hidden Blades and sent it upwards towards the gang leader's body. The gang leader moved back before the Hidden Blade made contact with the leader's clothing.

David lunged at the gang leader, pulling out his basket-hilted sword at the same time. The gang leader hastily defended against David's attack. David and the leader were trying to overpower each other with their swords. The leader quickly pulled out his pistol and aimed it at David. David had seen the gang leader pull out his pistol and had rolled away.

The gang leader sheathed his short sword, threw a smoke bomb at the ground and fled, reloading his pistol while running. David put away his sword and ran after the gang leader.

"Get him! He's trying to kill me!" the gang leader shouted to no one in particular. Two gang stalkers appeared out of the crowd and looked at David, reluctant to follow their leader's orders. Before the stalkers came to a decision, David had already run past them.

Pulling out his Queen Anne pistol, David pulled the trigger at the gang leader's direction. The round hit the leader in the shoulder, but it did not matter much to the gang leader. A moment later, the gang leader swung back and fired a shot at David. It missed David by a few centimetres and hit a civilian in the stomach. David would have stopped to help the civilian, but he had more important things to attend to.

David kept his Queen Anne pistol as he closed the distance between him and the leader. David took a stab at the gang leader with his Hidden Blade, but it missed. The gang leader stopped and continued the fight with David. Seconds later, David managed to land a strike on the betraying gang leader, but it was only a minor wound David had caused. The gang leader groaned and reached for another smoke bomb.

"Not this time," said David as he brought his sword down on the gang leader's hand. The gang leader howled in pain as his hand detached from the rest of his body. David finished the gang leader off with a stab to his heart. David kept his weapons and ran back to the gang hideout.

"What is it, David? Why have you returned so quickly?" Liam asked. David explained, "I encountered the betraying gang leader on the way back to my apartment. I killed him."

"Great job, David. At least they're gone," Hope praised. "I just hope there will be no more traitors in my gang."
