Frozen 2: Why did Elsa unfreeze? 

Elsa unfroze in Frozen 2, after Anna broke the curse by destroying the bridge that connected the people of Arendelle and the Northuldra Tribe.

Frozen 2 is the 2019 sequel to the 2013 breakout American computer-animated musical fantasy film, Frozen. Both animated films were produced by Walt Disney Animation Studios and were released by Walt Disney Pictures. Frozen was the fifty-third Disney animated feature film, while Frozen 2 marked the fifty-eighth animated Disney animated film. The story of Frozen was inspired by Hans Christian Andersen’s fairy tale, The Snow Queen.

Moreover, at the time of the release of the first film in 2013, Walt Disney as a whole was moving away from princess stories that placed the male protagonist as the saviour of the day. This was already seen with earlier princess Disney films like 2009’s The Princess and the Frog and 2012’s Tangled. However, these stories still had a romantic love interest at the heart of the animated films.

Hence, with the first instalment of Frozen, this narrative was turned on its head. This is as the story focussed on the bond between two sisters. Moreover, the film emphasised this point as Anna saved Elsa’s life, and in turn healed her frozen heart which threatened to freeze her entire body through an act of unconditional love, a love that was not a romantic one, but the love two sisters had for each other. The sequel saw a revisit to this notion, with a twist.

When Frozen 2 begins, Elsa is called by an unidentified voice into the mystical forest where the Northuldra Tribe were believed to have lived. Arendelle was hit by a cold wave, which Elsa believed would only be reversed if she followed the voice. Anna, living up to their promise to always be together, forcibly went with Elsa. Just when Elsa was about to make the final journey, she sent her sister back. At the final destination, Elsa found out that she is the fifth element and guardian of the Northuldra Tribe.

Moreover, she discovered that the cause of the curse over the tribe was the bridge. Having travelled too far, with her last dying breath, she sent the memory and key to breaking the curse to Anna. When Anna, through the enlisting of the Earth spirits, managed to break the dam wall down, Else thawed out, returning to life.
