Stoick sighed after Hiccup asked if Heather was his sister. He had hoped that this conversation would never have to happen.

"Hiccup," Stoick began, "it's a long story, you may want to sit down." Hiccup looked at him with a confused look on his face, but sat down nevertheless.

"It started a few months before you were born. Valka and I went to Berserk for a visit, and while we were there Oswald and his wife announced that she was pregnant with her second child. Valka volunteered to stay on Berserk to help her with Dagur while she was pregnant. I returned to Berk and a few months later Valka came to our house in the middle of the night holding you in her arms. When I asked her who you were and what you were doing there, she told me:

"The official story is I found out that I was pregnant while visiting Berserk. I didn't write home to tell you because I didn't want to get your hopes up because of the other pregnancies that didn't end well. I came as soon as I could after he was born."

Stoick looked at her questioningly, asking silently what the actual story was.

"Oswald's wife was pregnant with twins. However, she died in childbirth. Oswald said that he couldn't take care of two babies, Dagur, and Berserk all at once. So, we came to an agreement: he would keep Camicazi, that's this little guy's twin sister, and I would take him. She was the firstborn, so that's why she stayed on Berserk."

"Valka, how are we going to explain that we have a child now? And it isn't fair to him to have him grow up here, away from his family."

Valka sighed as she looked at Stoick. "I already explained how we say that we have a child. And it's more fair for him to grow up in a household where he is loved and cared for, instead of being neglected and ignored for his childhood because his father is too busy. Besides he even looks a bit like me."

Stoick took a few seconds to actually look at the child, and he started to smile at the child who was wrapped in a blanket in Valka's arms.

"What are we going to name him? Don't look at me like that, if he's going to stay here he's going to need a name."

Valka smiled, "What was the name of your ancestor who was small but made a difference in the world?"

Stoick thought for a moment. "Hiccup Horrendous Haddock. There were two of them."

Valka looked at the child, "Why don't we make him the third. Hiccup Horrendous Haddock III, son of Stoick the Vast and heir to Berk."

"Camicazi was the birth name of your twin sister. However, she got a different name when she got taken in by a different family."

"Let me guess-Heather," Hiccup said. Stoick looked at Hiccup and was able to see the anger growing in his eyes. Stoick nodded grimly as he broke eye contact with Hiccup.

"Did you know the first time Heather came to Berk that she was my sister?"

Stoick shook his head. "When news spread of Dagur sending his sister adrift, I assumed, like everyone else, that she had died. I had no idea that she had survived." Stoick dared to make eye contact, and saw even more anger than before.

"Were you planning on telling me this eventually?"

"No. Valka and I agreed that we would do a don't ask don't tell. Unless you asked us directly about this, we weren't going to tell you."

"I don't believe this. I mean, I really don't believe this. A lot of crazy things have happened to me, but this really takes the the cake. I mean, I just found out that you have lied to me my entire life and-oh." Stoick smiled, not hearing the hate behind the interjection. "This is why you ignored me throughout my childhood. You realized a little too late that you made a bad gamble. After all, you did tell me I was 'The worst Viking Berk had ever seen.' You just thought that you got the short end of the stick."

Stoick was on the verge of tears, even though he didn't even begin to look like it. "Hiccup, please, let me explain. We did it to-"

"Why should I listen to anything you have to say?"

"Because I'm-"

"Don't you dare say because you're my father. You are may things right now, but my father isn't one of them. You know what, you were right all those years ago. What you told me before you went to fight the Red Death: I'm not your son." With that, Hiccup jumped onto Toothless, gave one more hateful look to Stoick, and flew off, leaving Stoick about to cry.
