Fallon has a new "project" to latch onto, but Liam wants her to go away with him. He suggests Fallon 'take the high road' but of course that never suits her. Blake just writes off her accusations as "bickering siblings". Liam once again asks Fallon to go away and forget this whole vendetta....until....
Fallon: "Adam slept with your mother."
Liam: "Let's bury the bastard."
Jeff comes home from the hospital (a home that resembles something from Woody Allen's
Sleeper) though he's not really "recovered" (they've set up a 'hospital room' in his house). Monica and Cesil bring him home and guess who's draped over the couch? Monica is...less than pleased. It looks like Dominique packed a lot of luggage for this 'surprise visit' after 13 years of abandonment, but that's small potatoes compared to the emotional baggage the Colby kids want to unpack.
Monica: "Did you pack your Mother of the Year Trophies? I can shine them with
my ass." 
Liam and Fallon see Adam freak.the.hell.out when Liam mentions Alexis....so Fallon comes up with the best worst idea ever. Y'see, Fallon is apparently the only one in the family who knows Alexis has left the country, so....
You've seen Liz Gillies as Fallon. You've seen her as Alexis. But how about Liz Gillies as Fallon...impersonating Alexis?
Michael tries to get Cristal to implicate her and/or Blake in bribing that State Senator because the Feds don't think Michael's evidence is strong enough.
This episode's party is for the opening day of the Atlantix team. Fallon and Liam attempt to slip Adam a mickey in order to make him make a fool of himself at the party. Once again, Blake isn't willing to hear what she's telling him, and lord knows she's being a pest about it.
Sam and Anders are on the plane to the Maldives. Sam tries to get Anders to 'dis-engage' but it's not really happening. Besides, Fallon and Liam's Dirty Tricks Squad is pretty lame without Sam as their leader.
Dominique claims she did not come back sooner because she "didn't make it," and was embarrassed. All the tales of her singing success are just that--tales.
Jeff gives her a million dollars; Monica's head nearly explodes. Why'd he do that? To see if she will take the money and run, or if she really wants to reunite with her kids.
Dom points out how great it is to see Jeff and Monica are such a solid team...and decides to stay. Cesil seems much more mellow than when we last saw him.
Who says slap-fights are just for kindergartners? (Okay, well, just about everybody) Fallon is getting better at needling her brother (finally!).
Speaking of kids....Dominique's been making more than music while she was away. Yay, more Carringtons.
The FBI arrives at the party to arrest Blake, since the State Senator was wearing a wire. Fallon is in shock: "Oh, God, it's my Confirmation party all over again."
