Ezekiel was a homeschooled boy raised with no friends other than his parents.  Over the course of Total Drama, he was so determined to get the prize money to help his family that he ended up getting mutated into a silly, feral little creature.  He’s officially been healed.  Sometimes he still has those strange habits from when he was feral, such as sitting/sleeping in animal-like positions, forgetting words and accidentally just saying gibberish, and making small sounds.  He’s mostly normal.
