Rei follows her, carefully. She does not want to trip on any slippery rocks. The water is warm below her feet, where it slides out from beneath the stones and grass. She looks up at the rock formation, judging the weight and the angle, before taking a seat on top of a suitable pile. She listens to the hot spring as it babbles and bubbles. Watches steam clouds form and froth. Looks at the greenery as it sprouts. Mitochondria rolls herself into the water, bobbing along the top like a beach ball.

"It is peaceful here."
