It was the morning of Nightmare Night in Equestria and in the castle in Canterlot, Serena was happy as it was her favourite holiday as she loved celebrating it with her Mom and Dad plus she had magic like her Mom.
"Yeah tonight's gonna be fun, and we're gonna get candy." she said as she was going downstairs as Agnola chuckled seeing Alex bring mean.
"Hey Daddy, is Mommy asleep?" Serena asked him.
"Yes as she is the Princess of the Nignt remember and your Aunt is the Princess of the Day." he told her as he was taking her to MagicKindergarten today.
Serena nodded as she was hovering making him stunned as the dark blue allicorn filly had been trying to fly but was beginning to and knew Luna would be proud.
"Tonight's gonna be fun!" she said as her eyes g,owed with green light.
"You look so like your mother you know?" Celestia said.
"Yep!" she said calming down.
Agnola was seeing Alex shake at her but Luna wondered what was going on as she chuckled but were seeing her eat pancakes and using her magic.
"Sweetie go get cleaned up as you have school." she said as Serena was doing a loop de loop like Dash making Agnola chuckle as it was cute.
At Magic Kindergarten, Twilight was planning fun things as it was Nightmare Night tonight but worried about Serena since she was Luna's daughter meaning the other kids might be weird around her.
But she saw Serena with her friend's and sharing candy which was good but some of the other kids were frightened as Serena's magic accidentally flared up.
"Oops sorry!" Serena said feeling bad.
"It's okay.
You're pretty excited about tonight huh?" Twilight said.
Serena nodded as she was calming down but were listening to stories but Alex was quiet.
Later that night, Serena was having fun as she and her friend's were trick or treating but was sharing some with her Mom and saw others doing the same but were having fun.
Luna was understanding as Serena was coming out of her shell.
