"Luckily, Loki cannot have more children, Odin made sure of that." Hel said silencing Klaus. "And Fenrir and Jörmungander were also sent to a second death, so I am the only one who remains that can give birth to chaos that powerful. Me, and I guess the 13th."
"How could you not know mother?" Klaus insisted, earning another glare from Afton.
"All of your fathers are humans on purpose.
"I've done my part not to be a nuisance to Odin." Hel defended herself.
"So why did you let Sirius live then if he was a mistake! How could you let that much power exist!?" Klaus exclaimed.
Hel let out a sigh. "When Sirius was born, he shared half of my godlike glory and his other half should have been human. However, he was smaller than the rest of you, and sickly and I somehow wanted him to make it.
"I had never given birth to a sickly child before. Humans make me produce strong children." Hel explained.
