The Prince was in the bath until he became wrinkly, then he got out, dried off, and put his clothes on. His plan for the rest of the day was to read a bit, write some letters from his bed, and relax so that he was perfectly well tomorrow.
Riku could do what he liked, it was his choice. Sora had always given him the choice. If his choice was to waste him time working like a servant so he could buy himself and leave, then that was what Sora would let him do. He just...loved him too much to make him miserable. Still, he wasn't going to make himself suffer, either. He was the Prince. His people loved him, didn't they? At least Riku's time in his life had been beneficial.
The Prince came out of the bathroom after drying his hair as much as he could. He took the soup and tea to a small table with a blanket, and relocated to an armchair to finish eating it. "Thank you," he told Riku, for keeping it warm.
