Rumors and speculations continue to plague Disney's "Frozen 2" and according to the latest, Anna and Queen Elsa of Arendelle are not actually blood sisters.

Rumor has it that Anna doesn't bear supernatural powers like her ice queen sister because the latter is an adopted child. This rumor likely came from a fan theory from The Film Theorists, which further stated that it's "Tangled's" Rapunzel, not Anna, who's Elsa's real sister.

The link between "Tangled" and "Frozen" has been brought up several times when it comes to theories about "Frozen 2," and that is because the long-haired princess was spotted in Arendelle with Flynn attending the coronation of Queen Elsa.

Now, the theory presents compelling evidence suggesting that Rapunzel is the real sister of Elsa and more interestingly, they are fraternal twins. The two movies reportedly took place at about the same time and both Elsa and Rapunzel are also of the same age. Further supporting the twin theory is the genetics factor that was also explained in the video. Both Elsa and Rapunzel have blue eyes and blonde hair; both are also left-handed; and they are the only Disney princesses who have magical powers. The two also share something in common when it comes to their powers — they bring life.

In conclusion, Elsa and Rapunzel are actually the daughters of the King and Queen of Corona, the kingdom of focus in the movie "Tangled." As for how the twins got separated at birth, it was mentioned in the video that the King and Queen of Corona, upon discovering that Rapunzel was stolen for her magical hair, intended to protect their second baby — believed to be Elsa — by sending her to the neighboring kingdom of Arendelle so she could live safely with her new parents and away from "Tangled" villain, Mother Gothel.

As always, these are all interesting theories that provide a new perspective on characters. However, they are simply theories and nothing more. Only the writers of "Frozen 2" know the answer.
