Father & Son Twist

The Father & Son Twist was a twist on Big Brother Canada 2 

For the first time ever in Big Brother history two houseguests in the house were actually Father & Son, Those two Houseguests were Father Kai and his Son Lay. They were unaware they would be in the house together and decided to keep their true relationship secret.

The twist only happened once on BBCAN2 and has since yet to make a return.
