Vinsmoke Family in WholeCake Island arc

Hey..
According to the latest chapter..
It seems that Vinsmoke Jajji and his three sons don't know about Big Mom's plan..
Only Reiju & Sanji know about it..

So..
Do you have a prediction or speculation that you have in your mind about what is the next move for Vinsmokes Family (exclude Sanji) in this WCI arc..?
Please share here with me.. ^^

Vinsmoke Jajji did not aware of Big Mom's plan on them..
He just noticed that when the father is been shot by Dogtooth..
Does he got some action after this maybe to fight Big Mom or to runaway from WCI..?
Does he want to help Luffy & Capone to head off Big Mom..?

Vinsmoke Family is the most victim in this WCI arc..
But they not merely normal human..
They equipped with high technology gadgets..

Let explain this by situations:
i) Fight or runaway..?
- I think Reiju will stand with Sanji.. She will try her best to make Sanji leave WCI with SH.. But Vinsmoke Jajji and others.. Would they runaway from WCI or stay there and face Big Mom.. Did Jajji somehow the same level of Big Mom..? Or Jajji is just as same as Sweet Commander's level..? If they want to fight.. Who will be their opponent..?
- Everybody (theorist) want to see Jajji faces Big Mom while Ichiji, Niji & Yonji face Premetheus, Zeus & Napoleon.. But according to the place where they been located.. Maybe they include Reiju will face Perospero, Daifuku, Oven & Compote.. While their father can straight go & greets Big Mom..
- If they choose to runaway from that building.. Could they signal Germa 66 from that place while the horned den den mushi were set up by Capone that will jammed every signal or communication away.. Is there another way to escape..? Remember that Germa 66's ship is also like den den mushi.. Maybe Vinsmoke still got secret way (high technology) to send signal to Germa 66.. If that happen.. We will see that ships will climb Big Mom's castle to save them from there..

ii) Vinsmoke & Capone become ally..?
- There is a theory that mentioned Capone & Vinsmoke knew each other and plan for this event.. They want to head off Big Mom.. Yeah.. Vinsmoke Jajji don't know about Sanji will be killed by Big Mom at the wedding.. But he maybe plan something with Capone to head off Big Mom.. That is why Capone is still calm.. He got contingency plans in his sleeve.. They might know each other since they were from Underworld.. They could plan this about one year ago before Capone work under Big Mom..
- Or Capone & Vinsmoke will become ally in future.. maybe Capone saving Vinsmoke Jajji from Big Mom will make both party will makes alliances between them.. Yeah.. Capone hate to work under big names.. Maybe become ally is the best way for Capone..
