Fallon's trying to launch FSN, the Fallon Shopping Network as part of Fallon Unlimited. Her plan involves buying a building to house the studios which will also have a luxurious penthouse for her to offer (as an incentive) to some prestigious woman named Claudette who will hopefully head up the channel. She finds there is a "competing offer"---from Alexis. She wants the PH because of the high-profile location: "I could meet your next stepfather here!" The two engage in a dirty-tricks campaign to get the upper hand in the sale of the property. Fallon later notes that the location has views of both Fallon's office and "Adam's hospital". Alexis could "see" her kids even if they won't talk to her.
Cristal's hosting a fundraiser for that clinic she started last season and Dominique pesters her to wear one of the dresses from Dom's fashion line. Cristal gently rebuffs her efforts, since the dress Dom offers is kind of dull. She wants "more shoulders, more sequins". Liam, of all people, gives Dom a pep talk, since people told him he ought not go into investigative reporting but he refused to give up. Dominique stays up all night sewing on sequins (using Jeanette as the mannequin) and it looks a LOT nicer. Liam is feeling neglected as Fallon does all her business-stuff, so he needed someone else to talk to.
Blake is bothered because Senator North has sandbagged Blake's plans for an airport, but Sam shows up wanting Blake's advice on dealing with Leo, who has even barged in to take the suite at the top of the hotel to "make it the base of his operations". Sam doesn't tell Blake the "real" story of what is going on; they just have some fluffy banter. After another, more vague conversation with Adam, S&C seem to think that Leo needs to meet with a "small electrocution". They're not out to kill him--they just want to get him away from the job site long enough to finish planting listening/video devices to gather evidence. A few youtube videos later and Sam is a regular Mr. Sparky the electrician, and Leo is flat on his back in the hospital. But he wakes up and tells S&C they're going to "go for a ride" once he's out of the hospital.
They tell Adam about their quandary. Leo promptly goes "Code Blue" and Adam pauses a little too long with the electro-shock machine paddles in his hands. When Adam drops by to let S&C know the "bad news"---that Leo is DEAD--Adam has that disconcerting, weird look in his eyes that we used to see all the time. S&C have about ten seconds of regret, but then realize it was a kill-or-be-killed situation.
Blake is unsure of how to proceed against Senator North, at least until Anders drops in to point out Senator North has to have some dirt out there. The dirt (an illegitimate kid) gets the Senator to blink. In fact, it gets him to resign!
Cristal still doesn't want the (improved) dress, but moreover she doesn't want to have an entire ballroom of people giving her the "pity face". Dominique tells her that no one thinks she's weak. They end up eating pizza and drinking champagne rather than going to the ball. They say it's almost like having a sister. Blake later insists that she's still a bad-ass, then shares that Senator North has resigned. Anders is lingering in the background as Blake screws up the courage to announce to Cristal that he is going to run for the now-open Senator's seat*. She is thrilled.
Liam's sad-puppy face is seen again as Fallon continues to choose her business over her husband.
* When a US Senator resigns, the Governor appoints a replacement to complete the term. There is no election until after the term is complete, which could be anytime up to six years in the future. But this is DynastyGeorgia, so I'll overlook it.
