They are royalty, they love Freya's sister more than her, The parents decided to make Freya's sister the next queen that's why Freya is jealous, Freya's sister has water power's but Freya has Fire power's that's why The parents loves Freya's sister more bc she has water power's, Freya is always pretending to smile for pictures👑💎

  Queen (Mother): Alr test your power's sweetie

  King (Father): Yeah is okay if you fail you can always try again kiddo

  Princess (Freya's sister): I did it and i have water power's

Oh and the reason why Freya's sister has water power's and not Fire power's like Freya and her parents bc she was adopted
