A few thoughts on the chapter:
Hints pointing towards the traitor:
I wonder who the traitor could be. And I do not think it is someone from outside the circle of persons we came to know living on Egghead. In my opinion it could be only someone from the Satellites or Stussy. Because alone for the deactivation of the dome earlier you have to have at least an understanding of the technology and need operational knowledge. And then look at what happened when they were all gathered in the Labo. Phytagoras called and transmitted his position, telling everyone that he was to go up to the next level in building C. So, the traitor knew where to find him. And right after everyone is headed out, he gets targeted.
However, then there is the problem with us knowing that all Satellites and Stussy seem to be present either up in the Stratum or down there with the CP0 agents when the dome went off. So, from that perspective neither of them could have shut it down.
But: Remember the holographic images Vegapunk is able to produce? For everyone of the aforementioned persons it would be an easy task to make a hologram of themselves and use that as a surrogate so that everyone around them could be fooled into thinking that the person was still present. (And Oda would not show us how the holograms were working back then, if they were not going to be important in the foreseeable future.).
And from the just mentioned candidates one is especially suspicious. I mean Stussy. Back in chapter 1071, when the deactivation of the dome happened, we know that at one time, shortly before it shut down, Stussy was either not down there with the other agents of CP0 or at least Kaku and Lucci did not notice how she received a call from Dr Vegapunk – so this means she was unobserved for at least a little time. We cannot know how she could have gone into the control-room of the dome, but as we know nothing about the technological background/outlay of Vegapunk’s base, we could assume that there could have been either a secret passageway up or a method to shut it down from afar. Additionally, we have to consider that it was her, who let Akainu be informed about the SHP on Egghead – a true ally would not do that.
And then I consider the fact that Oda is specifically highlighting her presence and interactions. For example he gave her that one panel in which he made her say that she is worried about Vegapunk and wants to help searching for him, too. He didn’t do that with the other Satellites. But I think he focusses on Stussy, not just because he wants to make clear that she, as a former agent, wants to help with the search, but because he wants to let us know that she is searching for the Stellar (right after Pythagoras had transmitted his position). Here, he highlights it even in using Sanji (the little Casanova) as his little helper to embellish the fact in aforementioned panel. (Oda does this all the time – using his little helpers here and there. Especially Nami and Usopp are often seen underlining important things with their antics, if you have noticed - He also did it with the last chapter in which Shaka tells Stussy to sail with them to which Usopp angrily replied that he is not allowed to add people – I think those little panels will be important for the future.). And we do not know if Sanji went with her in the end – yet.
Yes, I am very suspicious of her and think she is still with the WG and just made sure Akainu’s command was followed when she put Kaku and Lucci to sleep. I think she is just acting all nice as a play to get the trust she wants, to roam freely and do her business - killing Vegapunk as their initial goal was, without colliding with the SHP and – as Kizaru mentioned in his first panel - making sure that everyone is not leaving the island [this would explain why Phytagoras was subjected to the explosion.]. And look: The dome is having another malfunction – it could be, as Shaka mentioned, the result of the Seraphim attacking earlier. But he would not call the malfunction strange in the same sentence, though.
Calculation for the (im-)balance of power:
After Saturn will arrive and is able to take control of the Pacifista, we will have this outlook:
On the side of the WG:
- Kizaru
- Saturn
- Navy fleet
- 50 Pacifista Mark 3
- Seraphim
On the side of Vegapunk/the Straw hat crew:
- Crewmembers of the SHP
- Maybe laser-weapons such as we see the dome uses
Undefined fighting-capabilities:
- The colossal robot lying in the scrap yard (I definitely think that somehow someone will find a way to operate the thing. There would be no purpose of Oda mentioning its use some hundred years back.)
Luffy’s and Zoro’s panel:
Take note of Luffy’s exhaustion – I think it will play a bigger role in the following chapters. Because I cannot think of another reason Oda would lay emphasis on his totally exhausted condition besides the purpose of being left there by the crew – maybe it’s the only purpose, but who knows … . I have a feeling that is not the case. Maybe future situations will have him need to perform bodily activity and he will maybe either fail those tasks or just barely able to do them. For example: Sprinting after a CP0 agent, even with seastone-handcuffs on, could be very difficult for him.
Thoughts about Kuma:
I do not know if he had his powers back then as a child. But considering, what the men beating him said it could be either:
Kuma is taking the pain from them and is receiving pain in return (it doesn’t have to be the pain he is extracting, and maybe he even doesn’t know how to transfer the pain onto others yet – maybe it is his unawakened DF-power and we only saw him using his powers of now as his awakened form)
Kuma is taking the pain by being subjected to the same treatment the men would receive (this would mean he is not using his DF at all)
