Since the end of God Valley, I've believed when we return to Wano for Pluton, and Linlin/Kaido return, we will see a flashback of their history we don't have, yet.
We have a brief bit of Kaido and Linlin's time as kids in Vodka/Elbaph, and then their time on Rocks. Then, with Kaido, we have a brief snippet of him meeting King. Everything else from Big Mom is Totto Land focused, and with Kaido is Wano focused, when it comes to their flashbacks.
We're missing:
-Kaido and Linlin's homelands/births (no proof Kaido was born in Vodka whatsoever, we meet him at the age of 10. We're missing 10 years of Kaido's life)
-Kaido and Linlin's crew building (outside of King)
-Linlin's marriages. Linlin has had 43 Husbands, and we only know of Pound.
-Kaido's lover/Yamato's mother (Gloriosa, which is why we're missing her history from 38-15 years ago. Gloriosa left the Rocks Pirates due to God Valley, and lived with Shakky/Rayleigh on Sabaody for a period of time, which, I imagine didn't last long because Gloriosa probably got sick of them flirting, fast. Then, 15 years ago, she rescued Boa, Sandersonia, and Marigold from their predicament after escaping Marijoa. 23 year gap here).
-Kaido learning about Joy Boy
-Linlin getting her Road Poneglyph (I believe she stole it from Elbaph)
And guess what? THIS IS ALL THE SAME SHIT WE'RE MISSING WITH SHANKS/TEACH
-Early childhood (we typically see Shanks and Teach as young kids/teenagers in flashbacks)
-Crew building
-Shanks meeting Makino, and Teach... yeah
-Shanks finding out about his mother, and Teach losing Eris
Imu during God Valley wasn't aware of the scope of the Devil Fruits thefts. Imu most likely assumed that if someone ate the Paw Fruit, they'd just use it to save their own ass. We can tell, because when Imu ordered Rocks to kill Eris/Teach, Imu believed they were dead, when in reality Kuma came in with the double clutch.
After God Valley, we know Cipher Pol made a mass report. For who, though? Why bother having Cipher Pol make a report, if it's going to be covered up so much? Because Imu wanted it personally, to personally make sure the Davy Clan was wiped out. And, guess what?
It seems Imu ended up being well aware, that a number of Davys escaped God Valley, due to Kuma. This further explains the CD grudge against Kuma: it goes beyond Saturn. Imu PERSONALLY wanted to RUIN Kuma's life, for saving the Davys on God Valley, via the Paw Paw Fruit. Teach's entire existence is Kuma's fault. Good chance that since Imu and Bonney are both on Elbaph, Imu will tell Bonney directly to her face that Imu, not Saturn, destroyed her entire life. Ginny's kidnapping? Imu ordered that shit, because Kuma freed the Davys, Imu's nemeses.
The Celestial Dragons live streamed the Human Hunt on God Valley, and spent days arranging the event; they would have video/photographic footage of most survivors.
Meaning, Eris WOULD be wanted worldwide. Same with Teach. Out of everyone, they would be wanted the most. And who hunted them down? Cipher Pol.
Keep in mind Imu DOES NOT want people to know about the D/Davy Clan, Imu pisses their pants at the thought like Orochi. This would not be a public listing. At this point, the WG went into overdrive censoring the Rocks Pirates and God Valley, to the extent Sengoku threatened Marines into not asking questions about it:
Eris's murder would have been a clandestine operation. After her death, Teach sought the only sanctuary he could imagine: Newgate, his father's Nakama, the one man who truly respected Xebec on his own Crew.
Xebec was after the Galleila Shipwrights, for, "One Big Score".
Kaido and Linlin, who Fujitora deemed "The Return of Rocks", allied together to get the Ancient Weapons. Well, Linlin/Kaido don't know about Poseidon, as far as we know. Uranus is clearly in Imu's possession. Like Shiki, as well, what Ancient Weapon were they going for? Pluton, the Ancient Battleship.
Ancient Giant Shipwrights = Ancient Giant Battleship. Elbaph is full of references to Gods, between Nika, and Loki. Pluton is also the name of an Ancient God, according to Robin. So?
The Big Score was Pluton. Each Yonkou mentioned here is tied to Pluton.
Even as a kid, Shanks was offering to help Oden open the Borders. I highly doubt Shanks doesn't know Pluton is in the country, as Shanks went to Wano in fear that Teach would invade. Leading us to:
Teach and Shank, Kaido and Big Mom. 4 Yonkou, all on God Valley, all destined to fight over the "God" Pluton.
This is when we will see their full flashbacks, intertwined. Both Shanks/Teach and Kaido/Linlin will have their remaining flashbacks occur at the same time.
Shanks vs Blackbeard will flashback to their fights together, and Teach eventually scarring Shanks. We'll see the difference in life, between Marshall Davy Teach fleeing for his life, and Figarland Shanks being raised with love by the Roger Pirates.
On Kaido/Linlin's end, I think Kaido will get Domi Reversi'd, and be killed during Imu's possession.
Domi Kaido vs Linlin, and Linlin and Kaido remember their Crew Building Days, their pasts, and their trials/rivalries together.
The pairs of Yonkou are tied together by God Valley and Pluton.
Shanks will fight for Wano, and Teach for Pluton.
Linlin will fight to stop Kaido once he loses his mind, like his Captain, Rocks, and his father, Harald did before him.

Shanks:
Oden's Nakama, who went to Wano to try to intercept Teach, whom he believed would go there. Oden was clear to the Roger Pirates about opening the Borders:
Even as a kid, Shanks was offering to help Oden open the Borders. I highly doubt Shanks doesn't know Pluton is in the country, as Shanks went to Wano in fear that Teach would invade. Leading us to:
Teach:
Now has access to Caribou, who has Poseidon and Pluton's locations, and is the son of Rocks D. Xebec. Teach Inherited Xebec's Will, and will seek to use Pluton to destroy the WG. This fully explains why the Rocks Pirates were on board with Xebec, as well: Teach/Xebec's plan makes sense. Pluton is real, and if activated, is capable of destroying much of the WG. At the least, it would allow Teach to negotiate with Imu directly, as an equal.
Kaido and Linlin:
Announced in Wano they planned to use the Ancient Weapons to destroy the WG. Since Pluton is in Wano, and Kaido's run the territory for 25 years, the weapon they describe is likely Pluton.
Teach and Shank, Kaido and Big Mom. 4 Yonkou, all on God Valley, all destined to fight over the "God" Pluton.
This is when we will see their full flashbacks, intertwined. Both Shanks/Teach and Kaido/Linlin will have their remaining flashbacks occur at the same time.

On Kaido/Linlin's end, I think Kaido will get Domi Reversi'd, and be killed during Imu's possession.
Domi Kaido vs Linlin, and Linlin and Kaido remember their Crew Building Days, their pasts, and their trials/rivalries together.

Shanks will fight for Wano, and Teach for Pluton.
Linlin will fight to stop Kaido once he loses his mind, like his Captain, Rocks, and his father, Harald did before him.
