10 years later..
"Haha," I said as I zapped my sister in the back repeatedly and flew around the room to get away from her.
"Stop it," she said sounding really annoyed.
"I was only having fun."
"That's what you said before and now the-."
Then they clamped a hand around her mouth and dragged her away from me.
I flew up to them but before I could activate my heat vision (which I can change temperatures with) they put a knife to her throat and said I'm the person who killed your parents and if you try to harm me I will kill her.
