Re: the ending and who actually killed The Frog, I personally think Jenny was the one who actually pulled the trigger. Kort might have incapacitated him with the thumb-hold, but I got the impression that Jenny was given the pleasure of actually killing him. She was simply too smug and self-satisfied, at the end... :wtf: His death was obviously privately sanctioned by the CIA, unbeknownst to the FBI/NCIS, but I think Jenny was actually the one who did it, in the end. That's how she knew Jeanne was never actually at the marina, because she was there, herself. She was so obsessed with The Frog, she would have gone to any lengths to get him... and I think she did.
