Jewel was scared. She never encounter a another Night fury. Hiccup looked at her, just like Toothless did. 

Although, it was such a massive distraction, all Jewel ever did was flew. Toothless decided to fly after the mysterious night fury, which he thought that he believed that he was the only one. 

Hiccup knew he wanted to go, so he made a tail to make him fly on his own, just for an emergency . 

"Here you go bud. Go after that dragon." He said. Toothless flew after her, as the black dragon did, he was amazed by the sight of seeing different species everywhere he looked. 

"Man, Hiccup would be beyond disbelief if he ever seen this." Toothless muttered, as that he looked for the mysterious night fury. 

"Moon!" Jewel said, as Toothless's eyes widen. Moon was looking directly at him, as if she was disbelief of who he was. 

"Midnight?" She asked, as he approached them. Jewel, however was confused. She never seen her adoptive mother being so casual-like, always strict with her. 

It was like another personality she never discovered before. Toothless said, "Wait, why you call me, "Midnight?"

Moon chuckled, as if a memory was resurface to her, as she looked deeply into his eyes. "Midnight, we were in a nest together. We always play together as hatchlings. 

One night, a group of wild dragons attacked us, I was scared, frighten if they would hurt me because I was helpless. I couldn't fly yet, but you, you stood for me, and you fought one of the dragons to defend me.

Watching you fight made me to make sure to protect you too. 

Then, one fateful day, we went exploring, just the two of us. You promised me something back then.

You said, "I have to leave the nest. But one day, we will find each other again. I really don't want anything happen to you. The Dragon Queen would be ruthless if we don't scout for food." 

"Midnight..." 

"It's going to be all right. I'll come back to you.. my love." 

Jewel never heard this story before, as Toothless's memory of that day came flooding back to him, from all those years ago.

"Oh, Moon. It is you! I never suspected that we'll reunite like this." He complimented blushly as Moon licked his cheek. 

"I never liked anyone else. My love is for you. Midnight, this is Jewel. But she has a secret as well. It's ok, Jewel. You can trust him. " 

Toothless titled his head, as that he wasn't sure what he would see. Jewel closed her eyes to transform from a night fury to human form. 

"No way.... " Toothless said, in disbelief.  "I'm so sorry that I startle you like that Midnight. I never shown my transformation to anyone else before. Moon was strict to not let anyone know the truth." 

"Oh, Moon raised you all by herself. I never met a hybrid dragon before. Wait, there is someone who I need you both to meet. " 

"Who?" 

"My rider, Hiccup Haddock the third, Chief of Berk. And I know your true identity, Jewel. But I wouldn't say it to Hiccup yet, as that if you tell him you're a hybrid, things would be more intense." 

"What is her true identity?" Moon asked. 

"Elizabeth Haddock. Elizabeth... you may not know this, but this is something you should know as well. 

Hiccup may be the Chief, but he's also your brother. " 

"My... brother..." She said, "But how could you be so sure I'm his sister?"

"Because.... he needs you, more than you ever imagine. By the way, you guys can call me, "Toothless." 

"Toothless?" Moon asked him, as if the name is foreign to her, unfamiliar with his new name. 

"Everyone calls me by that name, so, it's adaptable. " He grins. 

So by nightfall, Moon and Jewel followed his lead where Jewel sees Hiccup again. Her decision was to stay as a night fury until she was comfortable of revealing her true identity to him and her new home.
