Time passed by like the ever-flowing Ethereal River.
The friendship between the child of Hell and the children of Earth kept on growing deeper with time.
Though Lilith was initially hesitant to send her son to Earth with Theodore on a frequent basis, she couldn't keep her son tied to Hell when he enjoyed his visits to Earth to a great degree.
Theodore would mostly come to take Damien up on Earth during the weekends. And if there were any special occasions or festivals then Damien would be present in all of those.
"You know the drill, Damien," Lilith would fold her arms and would raise her brows at Damien every time Theodore came to pick Damien up.
Damien would hold Theodore's hand and reiterate what Lilith would always tell him, "Yes, mother. I know. Don't show the wings to unacquainted people, don't eat too much food because I will get used to it and will want more, be home by evening, and don't fight with anyone."
