I thanked the lady for letting me know that they were the finalists on the show. At first, I only saw two groups, Emblem3 and Fifth Harmony.
After further research I realized Carly Rose Soneclar, her brother Russell and Diamond White were apart of the van full of talent. The kind lady that I spoke to was Diamond White's lovely mom Debra White.
I just watched a few clips of Carly Rose and Diamond (both 13) and I'm blown away at their talent, fortitude and family. So I just wanted to say best of luck to them. Their talent speaks for themselves. I wish them all the best.
