Andy Rueda is reflecting on his remarkable “Survivor” journey. After being voted out by Rachel LaMont’s shocking idol play, the 31-year-old AI research assistant exclusively spoke to The Post about how he went from suffering a public breakdown on day three to masterminding his “Operation: Italy” scheme that nearly won him the game. “I’ve done a lot of work trying to process exactly how that happened, why that happened, like what was going on there,” Rueda said.
