After calming herself with what she had just learned, Irene then proceeded to untie Laura there. Right now what is important is for them to save themselves first. Other than that, she will think about it later. She can't be too emotional in this kind of situation.
"Done!" Irene said to Laura after the last knot opened. Laura then quickly get out from the rope and start to untie Irene. Her part is clearly easier as she can see the rope with her own eyes while Irene can't. So, she did it more faster.
"What should we do now?" Laura asked Irene as she massaged her wrist, which was clearly red, injured at the time. Irene then looked around. That room is a room without a window and there is only one door. There was nothing in the room except the rope that bound them before and a dimly shining lamp. There is absolutely no good ventilation there.
Irene stared at the door for a moment before answering Laura.
"We try to escape, of course."
