I dare not to say it: But I think
@Garp the Fist is right. And there is one huge little detail from the latest chapter that makes Stussy's allegiance now utmost questionable to me. (I still have not posted my thoughts about the latest chapter in the chapter's thread and therefore did not say anything here [I'm still working on the short story of Arlong finding out about Jinbe being on Luffy's crew - almost done]).
Stussy fans please - do not read, if you really like her:
Have you thought about the fact that York was working together with the government? She was determined to kill off every other Vegapunk and pushed the WG to investigate on Egghead, which in the end turned out to develope into in assassination attempt from CP0. It showed York's determination to end all the other Vegapunks!
But have you thought about the fact, that York also knows about Stussy being a spy for Vegapunk for over 20 years? Because York shares Vegapunk's thought through "Punk Records". And if York really did want Vegapunk dead, than she also needs to take this detail into account, because Stussy could have given Vegapunk the information that York and the WG plan to kill them, beforehand and prepared. (If you think about it in detail - Stussy could have given Vegapunk the intel on who it is, who wants him dead at the latest after Stussy officially rejoined Vegapunk in chapter 1072 - there was enought time and everyone was gathered there, before they split up in groups again - she did not do so.)
And if we consider that the WG did know about Stussy being a spy of Vegapunk, they did no act on the intel and send Stussy on the mission with Kaku and Lucci regardless. Isn't this a little strange to you? If the WG knew about Stussy, than they would have done something to prevent her endangering the mission. At least they would have informed the other CP0 members about Stussy's role, so that they could have prepared their mission accordingly. But Lucci and Kaku seemed to be very surprised about Stussy's "betrail".
My question is: Why did the WG not do anything regarding Stussy, if they had the intel from York or did York forget about informing them?
And if York forgot about telling them, why did Stussy not inform Vegapunk about York?
