You're not too quite sure when you first noticed it, but one thing you can say for sure is that your sister is...different. Not that she's "quirky" or whatever similar phrase one would use in this situation, but every day she "changes". Her appearance, her personality and even her age can vary wildly from day to day. Nobody else seems to notice it, but you can swear you've seen multiple separate versions of "Her". But to her and the rest of your family, Kayla is the same as she's always been. You've decided to just stop asking questions and just roll with it

It's a new day and Kayla has yet to come down for breakfast. You go upstairs and call out to her; you knock on her door whilst informing her that it's time to get up. You hear a loud grumble from the other side of the door but it doesn't sound like she's making any effort in getting up like you asked. With a sigh, you announce that you're entering her room; Time to see which type of sister you have today...
