The artificial human listened, as Tyler and Aetius spoke over the open communications channel. Well, not really open. But to those who had earned the right to be in Aetius circles would have full access, and be able to hear anything said. It was extended to those who had proven themselves exceptionally skilled in their particular field, or exceptionally useful in other manners. While 57 had some objections about Tyler's informality, he had to admit that Tyler was quite capable, in his own way.
But 57.... he worked a bit differently.
Normally, the moment Tyler had asked for reports, he would have reported instantly, but his current situation prohibited him from speaking so openly. Moving over the rooftops, he silently strode from place to place, ducking and rolling. He was capable of moving far faster than he did, but he wasn't trying to outpace his prey. While performing a routine inspection of the weapon's facilities, he had discovered that one of the workers had an unusually elevated heartbeat and breath rate, as well as having smelled perspiration. A certain amount of fear was usual, due to his reputation as a merciless killer. However, this particular quantity of fear had been sufficient for 57 to take notice, and to trail the person now.
he was moving quickly, and hesitated at a turn. he was looking around, wide-eyed. He was trying to find his way, which meant he was not going home - 57 had memorized the worker roster, and this man, Bill Whites, had worked here for 4 years, and hadn't moved. This meant that he was moving to a different location, which he was nervous about, and which seemed to be tied to 57's arrival. More and more 57 decided he was suspicious of this man. Normally, he would have arrested him, and had him questioned on suspicion of terrorism with the highly advanced and highly feared interrogation devices Helios had designed. However, this man had a purpose, and 57 would trail him to this location, and hopefully discover his associates. This could allow him to out an entire terrorist cell.
Of course, fighting might be required. 57's hand lightly brushed the hilt at the back of his left boot, where his spare knife was always kept. He'd be able to take down a number of enemies using simply this, even without his specialized armor. However, if they were using heavy-duty Combat Suits, or high-level metas, he would need better equipment to take care of them.
