And where is the line drawn? At what point am I Sanji, instead of Jixsan?

[He shakes his head.]

Maybe Sanji'll remember this history, but it won't make him me. I already told you, we're too different to be the same person.

[He can't help but be stubborn. Sora and Roxas are not the same person. Neither were Isa and Saix. Perhaps Lea and Axel could be considered close in personality, yet even here the Nobody can remember such clear differences.]

When he gets back, I'll be a memory.
