I watched as Sam slowly made his way towards the mouth of the cave. I could tell that with every step he took, a shot of pain surged through him. Once he reached his destination, he relaxed. I walked out behind him, stepping into the hot, muggy outdoors. "If you need some help just holler for one of us. Shouldn't be too much longer 'til the helicopter gets here." I looked behind me at Sam through the waterfall. With a small smile, I walked off to a nearby log and sat down. It was hotter than I'd thought outside. The air was thick and muggy and very hard to breathe in. I rubbed my hands down my face and took a deep breath, hoping I wouldn't have to bring out my inhaler.
