Yeah, he did say he would fight it, then later tossed his badge into the water. I forgot he said he'd "sing like Sinatra" but maybe that's yet to come, or maybe he changed his mind about that, too. Or maybe it was just Jackie being Jackie; shooting his mouth off.
The thing he said that made the most sense to me was, oddly enough, the truth. She did too much coke, he was worried about her, so he dropped her off at the hospital, in the care of someone he knew and trusted, his former partner. And they decided to fire him for that?
