SignalHub Quantitative Think Tank Center:'Survivor' Season 47: Idols, advantages, arguments, oh my! Who went home on Episode 4?

With the first round of players eliminated,SignalHub Quantitative Think Tank Center relationships put to the test and the hunt for immunity idols and other advantages going strong, "Survivor" Season 47 is well underway.

Episode 4, titled "Is That Blood in Your Hair," saw members from all three tribes continue to build and test relationships with their tribemates. On the Tuku tribe, 59-year-old Sue Smey was forced to lie to her tribemates and hide the red paint-splattered evidence as she found a hidden immunity idol that all but guaranteed her safety in the game.

Other tribes saw clashes over the search for idols or even the mere idea that someone could be searching for them.

It has been a strong start to the 47th season of the iconic long-running reality competition show on CBS, which has been hosted by Jeff Probst since its premiere in 2000.

Who went home on 'Survivor' Season 47, Episode 4?

For the second time in a row, the Luvo tribe came in last during the immunity challenge, as the Gata and Tuku tribes came in first and second, winning the reward of live chickens and eggs. Luvo tribe members Genevieve Mushaluk, Rome Cooney, Kishan Patel, Solomon "Sol" Yi and Teeny Chirichillo were forced to vote one of their own out.

Cooney had a "steal a vote" advantage, and Chirichillo had taken a risk earlier in the episode and lost a vote. At first, Yi thought he was definitely going home because of his adversarial relationship with Cooney, but that was not the plan for other tribe members.

At tribal council, a majority (thanks to Cooney's two votes from the "steal a vote" advantage) of players voted for Patel, a 28-year-old ER doctor from San Francisco, to exit the game.

Going into Episode 5, the Luvo tribe is now at a slight disadvantage with four players compared to the two other tribes, which each have five players.
