"Could mean something to someone, how I’d live to play that part!"
In both the beginning and the end of the movie, Anna is seen pulling someone while by the arm while saying “Come on, come on, come on!”. Now this could just be a coincidence, but it could also be a very crucial aspect of her character.
Anna is a bubbly girl who is usually overenthusiastic and over excited. I could easily see her pulling someone to show them something cool every day. But she hasn’t.
Anna was first pulling down Elsa so that they could have fun in the snow. So that her sister could be happy since she knew her sister loved to make snow. However, after this night, everything stopped. Elsa stopped talking to her and she couldn’t make her sister happy anymore. She probably thought that she even made her sister sad and angry. And she was alone. With no one to share happiness with…
After the whole adventure, Anna starts pulling Kristoff to show him his new sled. She is so excited even though the surprise is for him. Why?
Because she can finally make someone she loves happy again.
