Mizu's ears rangs as the two humans yelled at each other inside the cave, and he winced visibly. Noisy creature. His body relaxed at the sound of people stepping away from the entrance, thus silence came back to him. He noticed the mask that Nathan held, and listened very, very well to what he said, about saving this planet from complete destruction. Should he trust this man? More like, can he trust Nathan enough to let the human take him to somewhere that he never went? He lifted his head to look at the scientist with a bit mixed emotions, but he emitted an aure of sincere and Mizu, could tell that this man bring no harm. Not like the other. So, he nodded. "What should I do then? To become like your kind, I mean. The people outside might be very suspicious if you came out with..me." he asked, completely at lost about what he should do. He saw some of the bottles that Nathan put on the ground and took them. "I want a very detail explanation after this." He said. Mizu's face turned serious all of sudden. Sure, he would love to save his planet, or something but, he just can't jump on things that he didn't know.
