Despite the fact that Arthur had never, once in his entire childhood been held like this, he didn't struggle or ask to be put down. His mother had disappeared when he was young, and his father was never one for hugs or affection towards his young children, so the only thing Art had ever had was a hug. Except he liked this, he liked being held.
The lullaby, even though he couldn't understand it slowly soothed the boy and as he buried his head in Elisabeth's shoulder to hide that he was crying, his breathing began to come back to normal and the tears slowed in their tracks. Arthur closed his eyes, allowing the melody to calm him and ease his distress. He wanted to tell her, sleepily that it was going to be all right and that she didn't have to cry any longer but when he opened his mouth, all that came out was a yawn and it was then that he realized he couldn't fight off the sleep the lullaby was bringing him to.
