Ok I know this is probably mentioned somewhere on here already but I just thought of this now.
Anna resembles her mother Iduna who's from magic town, Enchanted forest
Elsa resembles her father Agnarr the king and son of the betrayer king of Arendalle
Anna and Elsa are each a side of the bridge to reunite both people
Is Elsa the leader of the magic town? Or just lives with them?
I know kingdoms have marriage to unite kingdoms because you're not going to fight the ur own family right?
But Elsa goes to live with them and she RESEMBLES the people and act all posh like her grandparents who were there opposing people. But now she's all loose and happy and not as posh.
Anna resembles the small town people who they are fighting, is 2nd born and usually would not have seen leadership her whole life. She was all not serious? Childish but she grows up to know responsibility. And now rules, Arendelle when she RESEMBLES the small town magic people.
This is another sign on the bridge thing and is super obvious right? I just like to ramble about obvious things really.
