Even if no one is around, you know better than to go running off to save yourself. No one is here NOW doesn't mean somehow someone isn't going to realize you totally abandoned your duty. You turn on your flashlight and start into the cave, cautiously moving because even with the light its still incredibly dark. You best watch your footing. "Help me!" the voice starts up again and it sounds closer. "Please! Please!" You hurry your steps a little because if what this person said, there was something wrong with their leg. You want to find them and get them out of this cave.
As you walk, your flashlight catches something – it's big and its got a lot of teeth. That's the only thing you register as you trip over something oddly fleshy and then...nothing.
