What was the relationship between Linlin and Kaido 40 years ago?

With the recent information revealed in One Piece Chapter 907, the question that arises to most people’s minds is what Big Mom and Kaido’s relationship with one another entails.

At Whole Cake Island, Big Mom contacts Kaido via Den Den Mushi, telling him to stay out of her way as she goes after Straw Hat Luffy, saying that she will be humiliated if she isn’t the one to kill him. Kaido refuses, citing his own grudge against Luffy and threatening to kill Big Mom if she interferes. Linlin then says that he owes her a great debt from a long time ago and insists that they cooperate on this.

According to Garp, their connection with one another stems back to over 40 years ago.

If Big Mom and Kaido were working with one another that long ago, it is possible that they may have had an actual “relationship” with one another. The main point I’m getting at here is that I believe some of the children in Big Mom’s crew are Kaido’s kids. More specifically Katakuri, Daifuku, and Oven. Katakuri, Daifuku, and Oven are all 48 years of age which is definitely more than 40 years ago. In addition to this, the resemblance between Oven and Kaido is uncanny. Their facial structure as well as their beards look almost identical when put side by side. They just look like father and son.

Yes, Katakuri and Daifuku don’t look as much like him, but they are triplets after all. Kaido as their father would just make sense based on how ridiculously strong the three are. Exactly what you would expect of the children of two Emperors. Hope you guys enjoyed my thoughts on the matter and feel free to join in on the speculation.
