He managed to slip into the foliage

Son of a bitch.

Now that you were out of the clearing, the jungle surrounded the makeshift path on all sides. Somehow, Will managed to slip out of the edge of the group and and into the jungle foliage, unbeknownst to your captors. You make eye contact with him as he slips back into the dense plant cover and stays still. "I'm here. Just give me the signal", his eyes seemed to say. Or at least you hope.

"Stop!" one of your captors commands. Your group comes to a halt. Clearly, they mean to kill you all now. Your time has run out, you need to make your move now.
