You all enter the small room, as Sarwyn (who has the lead I assume since she cut the whole) walks to the door on the far away wall she hears voices on the other side, talking in a language she doesn't understand. Rusky and Vash hear it too, Rusky you are quite certain there are three men behind that door chatting about something from the tone of their voices and the speech pattern you assume they haven't heard you.
Kan if you want to look for anything worth taking you are going to have to search for it, which will take a bit of time cause you didn't find anything after just a look.
