By
So far, we've seen brother vs. brother and mother vs. daughter match-ups on Survivor: Blood vs. Water, but now in our exclusive clip, we're seeing a husband and wife go head-to-head for the first time -- and the husband isn't holding back!
In our sneak peek, we see John, Candice and Marissa go head-to-head in a Redemption Island challenge, and John and Marissa are the early front-runners. Watch the video to see what happens!
Also in the episode, a castaway refuses to accept a clue to the hidden Immunity Idol, and another week produces another blindside at Tribal. Survivor: Blood vs. Water airs Wednesday nights at 8/7c on CBS.
