Yeah, I'm kind of loving that little side effect. I'm not a fan of the cliffhangers anyway. Sometimes, they feel so contrived and unnecessary. Drama just for cliffhanger-drama's sake.
I liked the episode overall and especially, that they surprised me at the end. I thought for sure that the quick response team would stop the killer and not a member of his team.
The biggest issue I had was that they let Sam call the shots. I know it's not the first time they've done it and I roll my eyes each time they put the least impartial guy in charge. (Although, I probably do that more when they put Sam in charge because he's not normally in charge, so they go through the trouble of putting him in charge even though he's biased). Yeah, the guys asked for him but if the Navy really wanted an impartial investigation there is no way that I believe that they would've let Sam have any say in the investigation itself. It should have been: do as you're told or get assigned a different case.
I would have preferred if they hadn't named-dropped Gallagher. The show has never been all that realistic, so connecting it to the real world felt kind of weird.
What was Fatima doing in Hetty's office? I think they should let us imagine that Hetty's around somewhere and not put a new agent into her office and raise the question of why Hetty isn't there when they're not prepared to address that.
All in all, I think it was a good way to end the season, though.
