You’re not sure what to do. You still have no idea how exactly you became your sister, and now your old body is banging in the door trying to get in.
Is he... your sister? Transformed into you? If that is the real Amber out there it would explain why she... Er he is so angry. He must be furious over you stealing your body. Of course you have no idea how this happen nor have you done anything to cause it, but that never really stopped your sister form blaming you and getting mad at you before.
You have very little time to ponder this very bizarre series of events. All of its is so confusing to almost making your head spin. However before you can think on it too much your old body speaks up for beyond the door.
“I know you’re in there you ltitle brat! Why have I turned into you? I know this is your doing, I heard my voice in there! What are you doing!”
Gulping you realise that awnser’s your question. Somehow you have spotted places with your sister, you now live her life and she now has your old life.
Your first instinct is to go out there and try to explain, mostly coming from your inherent fear of your sister’s wrath. But then another thought comes to you... you are your sister now. She no longer has any power over you.
And this is a great chance to not only get revenge on your sister but also get enough stuff to share with your friends that you’re never be seen as a wimp for the entire rest fo school.
Of course you’ll have to work out how to turn back, you don’t exactly want to be stuck as your sister for the rest of your life. But that can be something for future you to worry about.
Thinking over these possibilities you open up the door, having decided what course you would follow. You see your old body standing there clearly waiting an explanation.
