South Portland resident Bob Crowley has survived the first 10 episodes of this season on Survivor and pulled off one of the biggest tricks in the show’s history, but that could come back to hinder him as the show resumes Thursday.

Crowley gave Randy, another contestant on the show, a fake immunity idol during the last episode on Nov. 19, which Randy played after five other cast members voted to remove him from Gabon, Africa. The idol was fake, Randy was gone and Crowley stayed on.

Randy, however, remains in the jury that decides who ultimately wins the prize and said in a taped interview that aired on the Survivor Web site, that Crowley’s move sealed the Gorham High School teacher’s fate in Randy’s mind.

“People think that was a good move on his part, but the reality is I get a say in who gets the $1 million,” Randy said during the interview. “If he is one of the last three vying for the prize, I certainly won’t vote for him.”

Fans of the show aren’t so sure that Randy’s vote would hurt Crowley, 57, the oldest competitor in this season’s game.

“I don’t think what Randy thinks will matter to any of the jury,” said Gorham High teacher and colleague Jason Tanguay. “In fact, it could swing votes the other way if anything.”

While cast members have shown their disdain for Randy, Crowley might’ve shown a side to them they might not like, said colleague and Gorham High teacher Sally Hatch.

“I do think that while the tribe all agreed to use Bob’s idol to get rid of Randy, they may not trust Bob as much anymore,” Hatch said. “This may end up working against him in the future.”

Viewers will find out in which direction the remaining seven contestants will vote once episode 11 airs Thursday at 8 p.m. on Channel 13, the local CBS affiliate.

Through the first 10 episodes, Crowley has slowly risen to be a bit of a national fan favorite. Several blogs and Survivor forums have dubbed him as the man to beat with fans writing that they “really dig the physics guy.”

Crowley has consistently been the go-to-survival player of the game as he has fed his team by catching fish, sheltered it by building a hut and pampering it by building furniture.

Despite all those positives and regardless of what happens to Crowley on the game, he will be remembered for his deceptive and spontaneous idol trick, Hatch said.

“I think what Bob did was priceless,” she said. “It is something that will never be forgotten on Survivor.”

South Portland resident Bob Crowley, also a physics teacher at Gorham High School, sits with fellow contestant Susie Smith. Crowley, considered one of the most trustworthy players until this week, gave one of the other contestants a fake immunity idol.
