"Changes? Now we're physically changing?" Walter said, confusion becoming full blown panic. He looked over his body, but couldn't find anything wrong. Walter had indeed changed, but imperceptibly so, his skin tanning to such a small degree it was impossible to tell yet.
Nadine noticed her shrinking breasts as well. "Oh my! My breasts..." she said, too focused on her chest to notice as she began to grow taller.
Biff, meanwhile, watched in horror as his muscles continued to wither away. His skin had changed to be just as smooth and soft as Jon's as well, though that was not his primary concern.
Jon himself was taking stock of his body, when something caught his eye. It was the pool itself, the clear blue water bobbing idly in the sun. Jon had seen it since awaking at the pool of course, but this was the first time he noticed how refreshing the water looked, how sweltering the day was, how wonderful a dip in the pool would be.
His bodily changes forgotten for the moment, Jon began walking slowly, as if in a trance, towards the edge of the water, as he hair continued grow, now falling past his shoulders.
