Whiterose mentioned the it was time for Elliot to see that they were both on the same side. Perhaps Whiterose killed Elliot's father because he either knew he was molesting his children and therefore a major security liability or the project workers had reservations about what it was they were building and threatened to go public, the Ecorp board, or even the AEC like Angela attempted to do but was handed over to whiterose as a result. The poisioning of the workers giving them all the same cancer seems more deliberate now especially because two of the deaths had major ties to main character. The more I think ablut it feels like the workers on the project threatened to quit or unionize and went to Price with demnads who told Whotw rose there was little he could to do to prevent a walkout or from keeping them silent or to orevent the plant from closing. In response Whiterose engineers a toxic spill to covergiving the workers small cell lung cancer which is not treatable. Edward as software engineer was punished even further possibly because his loss set the project timeline back. So he was forced to quit or else evidence of pedophilia would be widely released to the public and the public. By quitting he couldnt afford medical treatment quickly and painfully. Angela's mother was also targeted especially because Whiterose knew she was having an affair with Phillip Price and her death would be extra satisfaction to pull Price's leash and tell him that when she tell Ohullip not to delay her project he shouldnt have to say it twice. Whiterose explicitly tells Price thay he has poisoned the workers and the toxic spill was a cover. Hence, the hatred Whiterose and espeically price have for one another. As a result of this knowledge Price decided it would be best tonstay away from Angela so Whote rose would not knnow ut was bis daughter. Her mom didnt want to accpet Prices help o forntreatment vecause she probably feared that accepting his help would lead to Whiterose making their affair public or they feared White rose would hurt Angela if she found out Proce was her father. Either way it would be traumatizing or fatal for Angela. Also wiuld gice extra meanijng to Whiterose's later dig at Price after 5/9 when she said Philip it isnt that had to ask it's thay I had to ask twice which Orice had heard before and would explain his anger of Whiterose's preoccupation with time.
