Theodore was holding Adeline's cold hand.
He didn't feel Adeline's pain anymore. But rather than believing that his wife had stopped feeling altogether, he believed that she wasn't feeling the pain because she was healing.
He kept on caressing Adeline's wet hair while humming the tune to the song that he had once sung for her. He wanted her to rest properly. He wanted her to heal completely.
Agnes wanted to make Theodore believe that Adeline had already left them for good. But she couldn't bring herself to say a word to Theodore. And she couldn't keep on watching Theodore waiting for Adeline to open her eyes either.
So Agnes got up from the fountain and ran to stand by the side of Arion. But her heart broke even further when she noticed a pool of water below Arion's head. He had been silently shedding his tears all along.
