A) We can’t assume she would immediately reveal anything to Luffy
B) She doesn’t have the whole story because *Oden* didn’t have it either
C) The rubber kid is still set to surpass all who came before him and in a totally different way, meaning his journey isn’t as similar to Roger’s as y’all wanna think

Yeah, I feel like there's just too much in Yamato's favour. A lot of her backstory and character conception are nakama specific.
