the thing about the Polish (or Husaria as they call themselves) is that they are way less of a united group than they might seem
Nexe is really the only one that treats the others as actual teammates (even if he bullies Ewron (they're kinda like an old married couple)) and shares information mostly equally, unless told not to.
Multi doesn't trust Ewron because Ewron doesn't tell him stuff, he only trusts Nexe and Graf, but also apparently trusts Quackity enough to tell him about the radiation leak
Ewron thinks he's playing 4D chess but I'm not sure he's even badly playing checkers. He tells the others he's spying but also doesn't share much info. He said before he'd choose Ash over Husaria, while also trying to manipulate Ash to destroy the Regime from the inside. And now he decided to side with Ash because the others are lying to him (Multi doesn't want him to know abt the Foolish kidnapping).
Meanwhile Graf is two timing Husaria and the North, offering to spy on the North and use his access to their house for invigilation but also telling Aldo about the distrust in Husaria
