Aqua could always manage to rouse the Sentiment out of his state of unresponsiveness. It was Aqua, he knew he was important to him, even if he didn't know how, just like that boy that was sleeping in the other room.

When she called to him, he stood up to see what she wanted, only to see her hugging the boy who was awake now? A flood of strong, unfamiliar feelings hit the Sentiment, feelings that he wanted to express, but just couldn't, he had no eyes to cry with, and no voice to cheer with. But it didn't matter, Ven was awake. The Sentiment joined Aqua in hugging the boy, because it was the only way he could express what he was feeling.
