Perseverance

Purple and blue

After that, Green showed the girls to their new room.
"Didnt green say something about when we have two major traits and colours, they mix to become a new trait and colour?" Pondered Milly.
"Yes,"  cara answered, intrigued.
"My colour, purple, requires your colour, blue, to make it. It also needs red. That means determination and integrity make perseverance. That's cool..." They both smiled. To be honest, neither of them new why they smiled, they just did.
That night, cara slept peacefully, however Milly was to intruiged to do so. No matter how much she tried to sleep, her surroundings were distracting her. Quietly, she crawled out of her bed and snuck round, sure that there was something strange, some kind of secret in the room. Why wouldn't there be? It all seemed quite normal though. Apparently, she'd stepped on some kind of trap, as the floor seemed to have somehow opened up and she'd fallen down into the unknown depths of the underground.
Cara awoke, the loud, squeaky trapdoor shocking her. She looked over towards the bed in which Milly had been sleeping in and gasped. Milly had gone. Cara new for a fact that milly had not left the room, for milly would never scare cara like that by disappearing at night. Cars snuck round, unaware of the fact that milly had fallen into the unexpected trap. Soon, cara fell too.
Milly was no longer there though. Cara new why. Milly's perseverance made her want to explore, no matter how hurt she was. Cara, however, did not have the perseverance to do so, only integrity. "Milly is lucky!" Cara thought to herself,"She has both integrity and determination, making her perseverance." Frightened, cara waited, hoping Milly would come back for her. Cara may have been strong, however strength would only help if she were to hurt those she encountered. She could not do that, not after what green had said. Plus she was hurt herself.
