This chapter was inspired by the scene in Lucifer when he and Rory(Aurora Morningstar) were in his penthouse singing and playing the guitar and piano.

Here's the link to the song from the episode:

Sunset held her guitar in her hands as she played the instrument. She'd decided to visit Equestria for a few days. She also wanted to see her mother. She'd learned a spell that allowed her to turn her pony body into her human one.

Zarachiel stepped inside of his room in Equestria to find Sunset there, sitting on a chair holding her guitar as she began to play it.

Zarachiel sat down on the piano bench and joined in with Sunset, playing the song on the piano as she sang. This song was one of his personal favorites. A timeless classic.

Zarachiel joined in, beginning to sing as Sunset started to sing the next verse of the song. He vowed he'd never betray nor harm his daughter. Ever. He was going to be better than what his father was to him.

Sunset had moved on from the Anon-A-Miss situation, or so he hoped. Her past didn't define who she was. Her past was not today. The past taught lessons for all the angels in Heaven. They'd remembered where they went wrong.

Both father and daughter sang the chorus at the same time, overlapping each other. Their overlap was a madrigal.

Sunset stared up at her father as he stared back at her. Zarachiel smiled and pulled Sunset against his arms as she snuggled into him, smiling as she closed her eyes, feeling relaxed and safe in her father's arms.

Sunset drifted off to sleep in her father's arms, a peaceful smile on her lips whilst she slept.

Zarachiel took her into his arms as he carried her to her room, placing her inside of her bed as he pulled the covers over her body. He wanted to make sure she was warm and comfortable enough. Nephilim had the body heat of an angel due to the angelic biology within them.

"I promise you, Sunset, that I will always be here for you. No matter what." He stared down at his sleeping daughter. Lovingly, he rubbed up and down her back, gently easing her muscles as her body relaxed completely. He felt over where her wings would be if they were out.

He felt truly proud of Sunset for finding new friends and forgiving her mother. But most of all, he was proud of her because she forgave herself. Both he and Lucifer could relate to how she felt.

Zarachiel walked out of Sunset's room and went to the throne room to help Celestia with Day Court.
