wdym not sure it can reverse the aging effect, it nullifies df abilities similar to what seawater does , without draining their energy however.you are in denial .look back at the scene where the strawhats saved bonney and you will understand why she was also described as a young girl.
only a couple people so far have referred to bonney as a young girl
and each of them know her real age .
Considering Oda created a lot of these characters 30 minutes before delivering the chapter, while taking a dump, I wouldn't be surprised if he never considered this "10-12 year old" plot to begin with.
I think it was
@TheAncientCenturion who sent a marineford page in which Doffy talks to Ivankov saying he "doesn't know how Iva and Kuma are related", despite the fact that last chapter we learned that both of them were two of the main pillars from the Revo Army. Also, during Sabaody, apparently it wasn't a wide known fact that Kuma was a Revo anyway, as he had to whisper it to Rayleigh, as if it was some sort of secret.
Bege killed one of his goons for no reason, only to be treated as a "caring boss" later in WCI.
The Supernova retcon is off the charts, so I wouldn't delve much into the "BB cancelled Bonney's aging" headcanon too much.
It's literally just fishing for something to go batshit crazy about for no reason.
