A third body is needed
Naturally, Quinn had also wondered about the name of the mysterious 'being' he had been talking to. With how boastful the voice had been earlier, it was actually quite surprising that he hadn't introduced himself. However, the tone of the other's voice after Quinn had introduced himself, had made it clear that the conversation between the two was over.
There had been no way for the others to hear what had just been going on. They had only seen Quinn place his hands on the tablet, it lighting up, and after a while he had let go.
Walking away, the dragon continued to survey Quinn with its eyes, but the vampire felt far less nervous. The voice in the tablet had seemingly kept his word and the dragon didn't attack him.
The others could see how calm Quinn was walking over to where they were, so eventually they came out to meet him, worried that the dragon might suddenly change its mind.
