They were both future kings , but Kevin did not like did not like his kingdom. He wanted to live in the royal kingdom, so his plan was to go fight for it. The king of dark said "no", "but I don't like it here," "Then leave".
Falling action/ resolution
As Kevin pulled up to the royal kingdom the air was fresh like it was hiding in baby's soap. The sun was smiling at Kevin. He started walking to the kingdom, the kingdom was suspicious it was way to quiet and peculiar.
As soon as Kevin entered the kingdom the doors screeched shut behind him and a voice appeared "hey what are you doing" then a fight broke out, fist flying everywhere. "I want your kingdom" Ruessel knocked off his mask "hey you look just like me"
"Wait your my brother and they sent you to the dark kingdom and me here" "well I just wanted to live here". "you know you could have just asked me, but you can live here with me even if things weren't fair plus we have some catching up to do".
