Not exactly Zoro related, but was wondering since latest chapter. Rayleigh said latest chapter that a baby reminded him of old days
That suggest that Rayleigh had a baby, and we know he is in a relationship with Shakky
And Shakky is 64 after the timeskip and mentioned to have left piracy 42 years ago(with the timeskip), just 1 year after Mihawk was born
And considering she was chased by Garp, it suggest she was at least resonably strong and seeing how her vivre card suggest she(and Rayleigh) helped the Boa Sisters to return to Amazon lily thanks to Gloriosa(former empress of Amazon lily 3 decades ago), it implies she may have some kind of link to Amazon lily, potentially the one of the 2 previous empress before Boa Hancock
Except that since she fell in love with someone(Rayleigh) she may have been forced to leave Amazon lily. Also if Oda really drew inspiration from the 7 heroes to create the Shichibukais,
Rocbouquet(Hancock's representative) and Noel(Mihawk's representative) are brother and sister, which we only find later on. So it's not impossible in the end that Mihawk may have a link to Amazon lily as well, and thus may have been Rayleigh and Shakky's son, which could also further explain the similarity in their outfit potentially to hint at the current wielder of the WSS title
