Wesselton had declared war on Arendale one month ago. Elsa and the kingdom were extremely worried. Even the wolves when they heard the news from the local dogs had stopped howling. An icy breeze blew from the castle. Anna was the person who was most affected by this. She stayed in her room, getting Gerda to bring up her meals for her. You would have thought Elsa would have noticed but she didn't. She was doing the same. When the sisters did meet they either said nothing or fought, the latter causing Elsa to run back upstairs back into her room chanting "love not fear," to herself. The only one who wasn't affected was Olaf ,who didn't understand what war was yet. He spent most of his time with Kristoff and Sven.
