DD16 and DD17 were chosen together in the same show. It was obvious to the adults int he group how it happened...
there were these two other girls about 13 or 14, who in the pre-show were trash talking my two girls very loudly, saying things like "get in front of those two b***ches, no way THEY deserve to be chosen". The parents were even encouraging them. The rest of us, including the TMs rolled our eyes.
As we entered, I saw the TM and the person giving the show exchange looks. She then made a very big and obvious production of skipping over the other girls and choosing mine to go together. She said "she could tell my girls had a very special connection, and they would be bonded by their wands forever". It was very sweet justice indeed.
