Dex Dexter - Season Nine

Season Nine

Dex has shot and killed Sean. In episode 199, he takes Alexis to Los Angeles to put this terrible time behind them and they make love. Afterwards, Dex tells Alexis that he's not interested in helping her repair the damage that Sean caused ColbyCo, but is ultimately drawn into the mess. He tells her that Sean invested millions of ColbyCo's assets in collusion with Alexis's comptroller, Fritz Heath, in order to bankrupt the company.

Dex meets Alexis's cousin, Sable Colby, who attempts to charm information about ColbyCo from him. In episode 204, he unknowingly sells Alexis's hotel to Sable, who plans to evict Alexis. A furious Alexis berates Dex for not investigating the deal more closely.

Earlier in the season, a body was found at the bottom of a lake on the Carrington property. The dead body turns out to be Roger Grimes, the man with whom Alexis was sleeping when she and Blake divorced. He had been dead for 20 years but the cold temperatures in the lake preserved his body. Dex suspects that Alexis has unresolved feeling for Roger when she vows to prove Blake killed him. Fallon asks Dex what he knows about the man-made lake, and Dex vaguely mentions that it was used to flood an abandoned mine on the property following a failed business deal between the Colby, Carrington, and Dexter families: Colterton Mines.At some point before this season Sam Dexter has died and Dex and Blake later agree never to reveal "the truth about the mine."

Dex continues to cross paths with Sable, in dealing with both the African tanker deal and the situation with the abandoned mine. In episode 211, Sable reveals that she was investigating the mine to determine what her ex-husband was hiding, and never meant to hurt Blake or Dex. She promises to abandon her investigation. Dex is attracted to her genuine regret. Unfortunately, Sable's henchman continues his investigation without her - and he's not the only one.

Dex rescues Sable from a deranged, gun-toting, Fritz Heath in episode 212. He comforts her, and they wind up in bed. Sable apologizes to Dex saying she respects his love for Alexis. They agree their fling meant nothing - but wind up right back in bed together. Sable and Dex want to protect Blake from Alexis - her quest for information on Roger Grimes will inevitable reveal information about the hidden mine that they want to keep secret. Dex assures Sable that his feelings for Alexis have never prevented him from doing the right thing. Ultimately, it is revealed that 8-year-old Fallon had shot Roger Grimes after finding him beating Alexis, and Blake's father Tom had hid the body in a mine under the lake to protect Fallon. The situation is complicated by the fact that the mine is full of stolen Nazi treasure, hidden there by Blake's late father. Roger's body had been disturbed from its hiding place by someone looking for the treasure.

In episode 219, Dex is shocked to learn that Sable is pregnant. Dex is upset when Sable indicates that she will raise the child without him. In the episode 220, the final episode of the series, at the Carleton Hotel Dex confronts Sable and Alexis for using him and throwing him aside. He mentions that Sable is pregnant, much to her chagrin. Alexis and Adam taunt Dex with the news, causing Dex to push Adam to the floor in frustration. When Dex turns his back, Adam rushes him. Dex falls backward into Alexis, sending them both crashing through a railing and falling off a second-story balcony while Adam, Sable, and Monica watch in horror.
