Why Blue Bloods' Finale Twist Is A Very Big Deal, According To Tom Selleck

Season 7 of CBS' Blue Bloods has been a relatively exciting ride from the very beginning, and it's poised to come to a pretty thrilling end in tonight's season finale. In fact, there will be some twists and turns that even star Tom Selleck didn't see coming. Selleck teased what's coming in the Season 7 finale, saying this:

We're leading up to a pretty serious confrontation. I don't want to tell the audience how it turns out, but there's a very nice twist in the show. I think it obviously changes Frank's life. I've gotten very comfortable with the notion that the writers come up with ideas when they formulate a story. They may come to us with notes, but I don't know where the character [will end up].

Tom Selleck clearly didn't want to give away too much about the season finale, but it sounds like we're in for one of the most game-changing confrontations that we've seen in Blue Bloods to date. The episode description certainly indicates that we're in for a fairly intense hour. The finale will be called "The Thin Blue Line," and it will see Danny get himself into some very serious trouble after he intercepts millions of dollars in drug money, and he ends up in a cartel's crosshairs.

And that's only one of the plots! Jamie is on the hunt for a serial killer who focuses his crimes on the elderly who cannot defend themselves, and Mayor Poole (played by Arrow's amazing David Ramsey) has a big announcement for Frank. Apparently, Poole intends to retire, which in turn would bring a lot of changes for Frank and the others. Tom Selleck went on in his chat with ET to say this about what the future will bring:

We have kind of a cumulative narrative on the show. Each experience [the characters] have informs them about the future. I think for Frank, as much as he's had an adversarial relationship with the mayor, played so well by David Ramsey, when push came to shove, they always found a way there. What has been happening in the show [recently], and I think planted some seeds for the audience, is that there's been something different

The dynamic between Mayor Poole and Frank has always been a personal favorite of mine, so part of me hopes that Poole's intention to retire is either thwarted or a ruse of some sort. Then again, his retirement would mean that Blue Bloods would go in some brand new directions in Season 8, and that could be a good thing. The series has already been renewed, so we do know that the Season 7 finale won't be the series finale. If Poole is taken out of the game, Blue Bloods will have to get creative to fill his shoes.
