@soreln Ray is the real "Y" that in this flashbakc is also the old man
Fake "Y"is the kid Jin bear didn't kill
Jin wants to control Great and also wants him to inherite all the powers of great, for this he needs to kill the "soul" of bear, and only leave the power for great
Y/ Ray wants to revive bear, for this "Great" was made but they need to kill great mentaly first. That way the "soul" of bear can be implanted in the boddy of great
Fake "Y" I think just wants revenge against the 2 of them, but im not sure
