It did not take long for Andy to realize he was lost. The jeeps were gone, Lucy was gone (thankfully), and now he was out here and the sun was starting to descend and the world was looking darker. More dangerous. Andy didn't know much about survival, and while he was a fit enough man from decent exercise, he didn't know if he could survive out here until morning. And what was more, he was becoming quite thirsty due to the dry air and the admitted mistake of not stocking up more on water.
Andy desperately called out for the jeeps, for anyone, "H-Hey! Someone! I'm out here, I'm lost, and I-I need...I need help..."
But he got no response, and there was little indication there was even anyone human to hear his cry for help. And as he kept on walking, he started to feel even more dehydrated, enough that he could feel himself becoming dizzy. He started to waver on his feet, and gripped on to a nearby tree, groaning from the discomfort.
He needed to find somewhere to get some water.
Andy started rummaging through the area for some kind of a clear enough water source, hopefully something not infested with microscopic life that would make his life a living hell. And as he searched, Andy's head swam. He heard Lucy berating him even though she was nowhere near him, and his only thought in response was that it was just his luck that even out here Lucy had a way of yelling at him.
Andy almost collapsed as he walked through a shroud of shrubs and bushes, breathing desperately and wetting his lips to try and fool his body. But there was no helping it. If he didn't get some water soon--- then his eyes were drawn to something. Very close by, there was something shining in the evening dusk, bright, crisp clean water in a vast pond or lake. Andy's breath was taken in sharp increments, and he dragged himself along the crisp sands and dirt.
The water was beckoning to him. He couldn't help himself. He would die if he didn't get some water in him soon.
He scooped up brash handfuls of the water in his hands and brought it to his lips, astonished by the clarity and purity of the water as he drank it down. He drank a few more handfuls before stopping, dropping by the side of the water. He let out a few bitter laughs as he wiped sweat off of his forehead. The water was crisp, delicious, and sated him instantly it seemed. Andy groaned and pulled himself back up. Distinctly aware now that his shirt and jacket were riven with dust and sweat.
He knew it was probably not wise, but he started to remove his shirt and jacket. Andy felt a strange, spasmodic tingle running through him. He didn't know where it came from, but it was odd in a sort of pleasant way. And in such a way that he wished it would finish.
Andy barely noticed as the light fuzz on his stomach thickened a bit, spreading upward to his chest. When his pants also felt unsettlingly tight and difficult on him, he kicked and took them off, not even caring right now. He was alone here after all. If he saw someone out here he could just get dressed again. He didn't notice his legs were also growing a deal hairier. His finger and toenails getting subtly sharper.
Andy yawned and unwittingly showed a few of his teeth looked a bit sharper.
The stranded explorer crossed his arms and mused about what to do from here when he felt the tingle seem to intensify for a moment, "G-Geez, what's the deal with this...? I hope I didn't drink anything bad. Shit this feels weird." Andy didn't even notice as he said this that his muscles were swelling, growing stronger, leaner, and more primed for movement and strength. Some stubble started growing in on his face mostly at the jawline, when usually Andy kept himself shaved up...
...And then it was done. The relatively minor dose had finished its work for the day. Andy looked down at his figure, wondering if he'd need to get a shave pretty soon. He contemplated from here what to do...
