Kain was beginning to panic, wondering if their only sign of help in a while had decided against the effort. After all, since this person was not one of their teammates, he really had no reason to help Kain and Serena.
For all he knew, Kain and Serena were horrible people that would turn on or kill him the second they managed to escape.
'Of course, I have no plans to do so…unless necessary."
Serena, still unable to understand the conversation grew slightly nervous at the prolonged silence, but decided to trust Kain to handle the exchange.
Then, finally, the voice returned. *"Understood. Give me a moment."*
Kain relayed the response to Serena in a low voice, keeping his eyes trained on the wall of ice in front of them that he felt the voice was coming from—but given how sounds can get altered as they travel through different surfaces, it was difficult to predict the man's exact position.
