Welcome back JC! I was very torn on whether he would be a hero or a villain, but ultimately, JC's ability to wiggle through tribals as time went on through Survivor Four: Virgin Islands classifies him as a hero. I think many see JC as sneaky, especially because he attempted to keep the fact he had an idol in his pocket a secret. If he can find his way on the right side of the numbers, I struggle to believe JC will be an early boot.
I think JC had a handful of small flaws in his game from S4, but he had the right mindset it took to win the game. He was helpful in challenges, constantly loyal to his allies, and in the end, I'm willing to give him another shot.
