No, put her right next to Cuban. When they show Cuban, they’ll have to show Flowers.
Cuban and Flowers can’t be seated literally next to each other. Each candidate will have his/her own section, side of the aisle as it were. All of HER guests will be on one side and all of HIS guests on the other. Nonetheless, there’s not THAT much distance between them. And IIRC the various family members have to sort of greet each other and shake hands and show signs of civility. So this could be one whole lotta fun.
