Wheein and the choreographer are really good friends and have been for a while. They go on trips together and everything. She showed up briefly in the WAW documentary talking with Wheein, they were practicing at the studio then going home and then chatting/eating. The dance group was members of Just Jerk Crew. If I am remembering correctly the crew performed and competed on America's Got Talent a long time ago and I am pretty sure that the choreographer, her friend, was a member that got to come here for that.... I don't know if any in this Wheein crew besides the choreographer were a part of that crew that came here for AGT or not.
