Does O'Donnel have his contract renewed? I know this is fiction ....... But, this is the 2 nd time they've had a PTS related killing by a main character and mysteriously resolved it the following season. (Gibbs killing the drug lord that murdered his wife & daughter in NCIS). If O'Donnel wants out then I can understand it.
I was mentally hoping he would pull the trigger but that doesn't make it right. He's my favorite on the show after Hetty - if either or both of them go, I will be disappointed.
