The black robed cultists would make their way over to Mikhail, and the first one, a tall one, although you can't see their faces, would draw a strange crystal out of it's robed sleeve ans wave it about. Maybe it's some kind of mumbo-jumbo, or maybe it's real- the crystal seems to change colors as he waves it about and he watches it knowingly. Or at least this can be assumed from the way he moves. He would look at the scientist and the doctor would tell you to follow him.

They would grab Sarah, much faster than they would you, and neither of you would struggle as they lead a dark haired boy- maybe a little younger than you, and begin the procession past the cages, down a tunnel further into the dark of the compound. 

Minutes would pass, other children- mines or tunnels you can't be sure. What you are sure of is a vibrating, a dull hum, not under your feet but in your head, and the farther down you go, the thicker it becomes. Somewhere on your right halfway down would be guards in a wide hall- the exit you'll have to take. Less than a minute more the kid in front of you would start coughing- and before the guard could prod him to move he would dip and trip him, sending him to the ground with a shove. Sarah would seize her guards stick and start beating him with it, quickly helping you after you'd trip him up. She would brandish it offensively against the cultists behind you, looking almost like a cornered animal, and the boy that had been ahead would start radoing to initiate the escape plan as he unlocked everyone's shackles. In the few moments this all took place the cultists would seem shocked but held at bay, and the boy would begin leading the escape.
