As for Harvey, he obviously wants to make sure that Mike wins the legal battle at all cost. He will do anything to get his friend off the hook even if it means breaking the law. He even asked Donna for a list of the jurors in Mike’s case. But Donna does not want to be a part of Harvey’s covert plans to save Mike.
Meanwhile, showrunner Aaron Korsh explained recently why he chose Shiela as the person who ratted out on Mike because there is no other character in “Suits” that has any strong reason to turn Mike in.
He disclosed that the writers of the TV series came up with several ideas. But they also suggested that the characters would want to harm Mike to avenge him or to gain some personal advantage.
Korsh and the writers could have chosen the parents of Rachel as the ones who turned the brilliant para-lawyer in because they have long wanted for the law to catch up with Mike
According to the executive producer, they picked Shiela because they wanted a character who would find out something and in response, do something that can be considered the right thing to do.
