i like how oro now sees naruto as a threat when he use to just think of him as trash. if oro isnt killed i can only think of 3 people who would be the ones to kill. jiraya being number 1, naruto being number 2 and the 3rds grandson has the most reason to kill oro. since the 3rd is the only family we know of he has. so i see him training hard as hell now that his grandpa is dead.
