As Kurt was leaving she said "So did that necklace cause me to change?"
"That's right" Ted said "Your not the only one that was affected, we're going to take you to the others while we look for the medallion" he took a bit before he continued "with luck we will be able to get you changed back, if not we will help the lot of you as best as we can."
Kurt stopped "Wait a minute, how many more are there that this girl has affected."
Ted said "Keep moving, its not the girl that's the problem its the medallion you all just happened to touch items of clothing that this girl had on which caused you to become a copy of her. As for the second part of your question you make number 7 that has been affected so there are now 8 copies of you.
