Sarah opened the door while her mother and sister fought it out over something.
At the door was a mousy girl, with her eyes closed.
"who are you?" Sarah asked, wondering how she got past the gate.
"I'm your new best friend." Zoe said, hearing the voice of a teen girl and opening her eyes.
"oh, wait.."
suddenly the world threw up, color flooded her view, she shifted and shuttered as powers fell upon her. In the multiverse there were many places where Zoe was a cheerleader, was popular, a fan of pink, an enemy of goths, a bitch, where she was what Sarah was to this world. The magic created a bond between Zoe and Sarah and when it was done Zoe was no more and Zoey stood in her place, a sophomore girl come to learn the ways of popularity and cheer leading from her mentor Sarah McMillan. She used to be friends with Sarah's younger sister Beth, but when she went all weird and arty she started to move towards Sarah more. She was more popular, that was important.
Zoe was plain, pale, unexciting. Zoey was tan, tempting and ambitious. She wasn't a bombshell but she knew how to make it seem like she was, and she idolized Sarah and everything she stood for, and Sarah loved her for the adoration, and was making Zoey into her heir. Now if only Beth would see sense and join in.
