To BellaCullen931, Thank you so much! The reason why Elsa hugged Anna was because they both remembered their mother and so hugging was the first reaction. I know Elsa wouldn't have done that but they're all each other has left . I also wanted to show some sisterly love between the two since we don't really see that much of it in the movie. ( Wow that was a long reply )
To Elsa Tomago, As I stated above, I wanted to show how Elsa still loved Anna and to show that they were still grieving. I included the Royal family of Corona because I like the idea of Agnar and Primrose being siblings and Agnar inheriting the throne of Arendelle.

Now to the story!

Can I say something even crazier? Ch 2
The next morning, Elsa was woken up by Anna knocking on her door. " Elsa? Please let me in! It's your sister, Anna! Please open up! " Elsa remembered Anna knocking on her various times as a child and got reminded of striking her sister. " Umm...I'm getting dressed! I'll be in the throne room in about thirty minutes! " Elsa shouted at her door. " Okay..." Elsa winced. There was a hint of sadness in her sister's voice.

Anna started walking away from Elsa's bedroom, holding back her tears. She ran to her room and locked the door behind her. When she was sure nobody was near the room, she broke into tears.

Elsa walked passed Anna's door and she swore she could hear her sister crying. She shook her head, thinking she was hearing things, and walked to the throne room. Expecting to see her perky sister, she smiled, but quickly frowned when Anna didn't show up. " Gerda, where's Anna? " she asked her old nursemaid. Gerda curtsied before her new queen before replying. " Your Majesty, Anna's crying in her room. She won't let anybody in there to comfort her, not even myself. Maybe if you went..." Elsa ran towards Anna's room. ' This is all because I didn't let her in earlier! Dammit Elsa! Be a good sister! ' She enjoyed thinking to herself, but not right now. Right now, she had to comfort an eighteen year old. Elsa knocked on the door like Anna always did on her's, but there was no answer. " Go away Elsa! " Anna screamed. " Anna, I'm sorry! " Elsa said. Anna was fed up. " NOW YOU KNOW HOW I FEEL! JUST LEAVE ME ALONE! " Elsa started blinking, unsure of how to respond. " Fine. I'll let you calm down. " Elsa stomped back to the throne room, letting her gloves frost up inside.
