You fabricate a torch and light it with your lighter. It gives off pleanty of light to see your way as you enter the tunnel. At first the floor of the tunnel is flat but then you come to an area that starts to rise upwards. Then in the distance, two figures appear about 100 feet in front of you. They are carrying a flashlight and walking away from you. Could this be the doctor? Who is that with him? Do you want to yell out for them to stop, have one of the prisoners yell out "help" to try and trick them, or just start running after them?

oh shit, i'm all for running towards them with caution and weapon in hand (and possible questions if they appear friendly/afraid)

i concur

if we run toward them..we do have a weapon in hand...our torch is the crowbar....i'm with you guy, though..just wanted to state the known
