AJ & McCall: Turned Down Bride and Proposals Debate @8

Siblings fighting is natural but what about when a wedding is involved? Sister one helped buy the dream wedding dress for sister two but alterations are needed. The bride wants help, the other sister says lose the weight. Who’s the jerk for the Debate At 8? What if during all this time off they had decided to call off the wedding? How would AJ & McCall react to called off proposals?
