I'm hoping rather than dead, Cliff just returned to his OG world or whatever. Cause wasn't there talk of how they can only stay in other worlds so long before they grow too weak? So if Cliff HAD to leave, but Leon has finally given up hope on ever seeing Cliff again... Maybe it'd have the same result?
Hmm, I don't know. But I think Leon never gave up...Cliff is his reason for living, even now, if he clings to life it is in the hope of seeing Cliff again. Then, Cliff is a bastard, he didn't say anything to Léon, which led to this situation.... Besides, I no longer even have the hope of seeing him again in the story at this rhythm...
Don't tell me that cliff is dead and that's why Leon lost his powers.... Now Mephisto tricked Leon by giving him a sleeping potion so that Leon could use it on someone and trap him? We know that Leon will try to escape using it. I think he'll use it on Beryl then have sex with it to steal his mana. Same when Leon swallowed Deus' milk, it was to obtain his mana probably....
