They really had no clue who could be there, and it would be impossible to figure it out solely by guessing from here.
Not only that, but the whole situation seemed to have become even more mysterious and frightening to them.
As fear continued to grow, they would soon find it difficult to think rationally about anything, making matters even worse.
Like Price suggested, they might as well just ask if there's really someone nearby. If that person could respond, maybe they could help them get out of here.
If there's no one nearby, then it's just their imagination playing tricks on them.
After carefully considering it for a while, Suri Drew and Yigol Novak both agreed that trying this method was useful, and they immediately nodded.
"Of course, no problem."
Instead of continually being scared as they were, it would be better to try out Price's suggestion.
Seeing their agreement, Price raised his voice slightly and shouted towards the source of the noise.
