As soon as they were outside the gates of Arendelle, Elsa turned to Adan. But she didn't need to say anything. He had already started talking. "Okay. I know you all must think of me as the bad guy," he said. "But my siblings had actually put me to the task."
"What do you mean?" Elsa asked, confused.
"We just recently heard about you having powers. My brothers were already jealous that
I had powers. Hearing that someone else had powers made them furious. They-they wanted me to eradicate everyone with powers and maybe gain the powers so I can give it to them. They suggested I join up with Hans, who is actually our cousin," he explained, ignoring Elsa's shocked expression when he said the last part. "I will admit, I originally wanted to go through with it. But, when I met you, I couldn't find the courage to kill you. So, when I accidentally burned you on the first day of training, I realized that I didn't have to. I could just hurt you, and you would lose your powers. But, after I did so, I regretted it. So when you asked if I come with you to help, I agreed."
(Okay. Just came up with ideas for this as I wrote it.

Sorry if it sounds bad or something.
