after the blue Team (later called 'the sinkers') lost in the first episode they were up for elimination, everyone (except box because well... she's lifeless) voted for blueberry, though little did they know that he had immunity (and MePhone4 wouldn't really reveal it at all for "plot twist purposes").

mephone4: "so that's two votes blueberry. one vote lifering. Two votes box. One vote left. And the first contestant eliminated is..."

everyone waited anxiously, though blueberry had no reaction, then, MePhone4's screen stopped on...

MePhone4: "box."

everyone (except blueberry of course) gasped in shock, what did box ever do to them? They still treated box like she's alive even though she isn't. They looked at blueberry in surprise, who just shrugged in response.

blueberry: "I don't know, maybe someone else voted for box."

he said, letting out a deadpanned "yay" as he fell from the tree stump and faceplanted on the ground, on the outside he didn't feel satisfied or dissatisfied that he was suddenly still in the game, but on the inside, he was satisfied his plan worked, no one knew he had immunity at all and they were surely convinced that it was just 'sheer luck.'
