In the time it had taken Dinah to wake up from the gas dr. Crane had used on her, Bruce had been gone and had come home. He had been out exploring the city, planting more of his organic tracking chips at places he hadnt yet been, and finished the other prototype watch that he'd been working on, the one that was oddly identical to the same one he'd given to Dinah. Of course, he had no idea of the events that had taken place at Arkham asylum, nor was he aware that his new friend Dinah was being held in one of the many rooms that the warehouse held. Of course, his room just happened to be next door, currently, to the one Dinah and enigma were sitting in, so he could hear their voices very vaguely through the thick walls.
Why did both of the voices sound familiar? He made it to his room, the one with the green stripe across the door, listening quietly to the murmur of voices in the next room. He had beer heard the voice of any other woman in any corner of this warehouse. That meant either enigma had made a friend that was female that she trusted to bring to her hideout, which was unlikely, or that there was someone here against their will, which seemed most likely.
Bruce definitely wanted to know what was going on. Leaving his room, Bruce walked to the room where the voices had come from, paused and knocked on the door, "enigma? Is that you?" He inquired, wondering why she would have someone else, particularly a female, over. Strange.
