On a very special day, 2 identical girls were born. Their parents, later, learned that they had powers.
Knowing that these girls had powers, a rich scientist adopts them and starts developing their powers.
Yes, umm, we've come to a conclusion that these kids will be better off with people that know how to deal with these situations.
As the girls grew up, one of them, had awesome powers. She could say any rumor and it would become reality. That's why, she was later on called The Rumor. The other girl simply didn't have any powers. As no one really knew her, she was simply named The Girl.
I am so proud of your sister!
One day, she overheard the scientist saying...
What you have to understand is that she's a bomb. She has way too much power to control. One day she'll just explode.
She got so outraged, that she challenged her own sister...
