So I been going over the big mom orphanage kids in the latest chapter.
I think they are some clear hints to who is the father to her different kids.
First we have this image of a bunch of rascals. All clearly destined to be pirates and it make sense (so far unless she kill them all in the next chapter) that they would join Linlin to go out in the world.
The most obvious connection is this women in a panda suit
As we got a panda suited kid behind mother Caramel.
They are clearly related.
Then I am guessing that Charlotte Mont-d'Or but that for me is just a guess.
More importantly I believe that Perospero father is the kid with a similar personality to him and they do share the same lips and overall body shape. And color scheme of their clothes are somewhat similar as well.
Then I think its Daifuku´s father in the small picture of all the kids, they share the same buzz-cut. They both got the same striped clothes(shoulder on Daifuku, t-shirt on the kid in the flashback)
Ok now lets get to the good stuff its 2 kids who are more prominently features in the flashback.
This a little edgier kid, who got a scare on his face and a feather shoulder outfit. I would guess is no other then
Katakuris Father. Same hair, color, similar design and that kid has the most panels. Makes sense he would be father to a commander.
Lastly we got the other kid with more panels.
The prince, which obviously then would be the father of Cracker.
They go the same eye pupills, ring then a pupil and a similar hair color. Cracker hates direct physical damage, which would fit his noble prince father who seems to be scare of direct confronts in the flashback.
