It seems that The Iconic Duo have their focus firmly on the SmackDown Women's Championship, which is now around the waist of Charlotte.Author's takeThe Iconic Duo has only been on SmackDown for a few minutes and they have already played their part in making history by helping Carmella to cash in her Money in the Bank contract successfully. The women stated that they were the future and given their history on NXT, it's hard to argue with them.
