Disclaimer: After a long hiatus trying to come up with ideas for my second fic, I HAVE IT! While Elsa's exile in the movie was of her own accord, what if Anna was exiled by the townspeople by extension of being her sister & how would Elsa react to this news? The Frozen brand & characters are owned by Disney & I do not intend to make any profit off of these fics.
"Elsa, please! I can't live like this anymore!" Anna was begging her sister to come to her senses & end her self-imposed exile but however, the new queen was having none of it.
"Then leave", Elsa ordered Anna, trying to hide her regret in saying those words but on the other hand, she would have no clue that the following events would lead Anna to join her in her upcoming exile. As Elsa tensed up further on her way to the door, Anna kept pushing her sister, demanding why she kept shutting her out all those years but Elsa, as usual, remained so reluctant to even converse with Anna (even though they had a brief conversation earlier on) so she brushed it aside with an "Enough, Anna".
"WHAT ARE YOU SO AFRAID OF?!" Anna finally shouted to the point the guests to the coronation ball stopped to look at the sisters squabbling.
"I said ENOUGH!" Elsa shouted, accidentally creating an ice shield to protect herself. Realizing what she had done, Elsa took off for the mountains.
"Elsa, WAIT!" Anna shouted after Elsa's back & luckily, she had Elsa's attention but it was only for a short time. Silently mouthing "Good-bye, Anna", Elsa ran outside, ordering the townspeople to stay away from her because of her powers. After Elsa ran off to the mountains, the townspeople turned on Anna, thinking she had something to do with this.
"Are you in on this?" one asked suspiciously.
"No! I swear!" Anna tried to plead with the man, but he remained convinced that Anna must have had powers like Elsa.
"You're her sister, you must have some part in this!" another brung up & by this point, the townspeople were fully convinced that Anna had conspired with Elsa beforehand in regards of the events of the coronation ball. The idea was like 2 strings in a knot: Anna had powers & conspired with Elsa beforehand in regards to the proceeding events.
"We KNEW something was up! Why would the late king seal the gates to the entire kingdom if they had daughters who were BOTH MAGICAL!" one man raged on, pointing a finger at Anna.
"You're wrong! I don't have any powers, I'm just ordinary!" she tried to explain but the townspeople won't have any of it as they were still thinking that she had conspired with Elsa beforehand.
Anna had two options: stay in the kingdom or follow Elsa to the mountains. The townspeople were for her leaving again because of what they convinced themselves & while Anna was willing to leave the kingdom, someone had to take over the throne of Arendelle. Elsa had also technically abdicated the throne of Arendelle which would result in Anna becoming queen.
"I can't leave", she told the townspeople. Upon hearing this, one lunged at her but was immediately held back by his companion.
"Get. Out", the companion said so Anna finally conceded & with one last look at the kingdom, she fled to the mountains herself.
Meanwhile, Elsa trudged up the mountain, sure that Anna couldn't follow her but unbeknownst to her, Anna was cast out from the kingdom & was coming up the mountain in a short second. What would she do?
