Pete Carmichael Jr will be coming back for Revenge

What does he have a cause for revenge? He got fired from a job he didn't even want. to begin with. As soon as he said he didn't want the job 2 years ago he should have been removed from consideration. That is my main objection of DA as HC. I don't know for sure he was insisting PC be retained as OC or if it came from Loomis or Lauscha but DA should have insisted not to retain PC as OC or turn down the HC job.
