"I think for the first time you're going to see some praise for being lied to, because Derrick for the most part is an all-around nice guy who nobody dislikes," Chen said of the BB finale.
Tonight's BB competition starts with contestants dangling from a hang glider in a storm -- the type of physical feat one might expect on Jeff Probst's show -- Survivor.
The survival competition show has a few tricks up its sleeve, and Probst shared one huge twist for this season.
"In each episode, loved ones will pair up against each other in a one-on-one challenge," said Probst. "If you win, your husband goes to Exile Island, so the only way for you to succeed is by sending your loved one to Exile Island."
