Snow

Snow once wandered off...

She stumbled upon a creepy cave. Bats were everywhere, and there gigantic spiderwebs in every corner. Not looking, she got stuck in one. Snow tried to call for help, but a huge spider appeared and bit her. Snow screamed. The spider poured the blood into a vial and shook it. Then it crawled away. Two hours later (at least it felt like two hours), the spider came back to her with a white lion cub like her. It had blue eyes though- not like hers. The spider said in an eerie voice, "Enjoy!" then stalked off, leaving her dazed. She tried getting off the web, but she couldn't. The cub saw she was trying to get away, and bit at the web, so they escaped together. When Snow got back to her mother, she tried to explain. But no one believed her. So she just brought the cub in one day during training, saying she "found it" and decided to name it Frost.

As Snow grew into a lioness, Frost didn't. Now Snow and Frost are practically sisters, but Frost is still upset that she can't grow, so upset that she refuses to speak with anyone. The reason for this is that she is a clone of Snow (except for the eyes, which are blue since everyone is born with blue eyes, and she's technically still a cub), and is stuck in time. Snow and Frost have now grown apart, still sisters by literal blood, but they don't usually interact with one another. Snow because she thinks her sister will hurt her if she tries to talk to her.
