"Since he is within the black mist, what is his current condition? Has the black mist affected him?" Frode asked.
If it could be confirmed that the black mist had an effect on Lisa's brother, then they might be able to infer the function of the black mist. This was Frode's thought.
Angel pondered and said, "His condition is a bit off. Based on current observations, his eyes are lifeless, seemingly bereft of sanity. Inside, he wanders like a walking corpse. Yet, no matter how much he wanders, he never leaves the range of the black mist."
Angel's statement was derived from observable appearances. To deduce what the black mist might do from such a statement was, for the moment, impossible.
"So you're saying that you can observe what's happening inside the black mist?" Sanders asked, "Apart from Lisa's brother, are there any other anomalies inside the mist? Can you identify the source of the black mist?"
