Reva, Josh and Cassie investigate Sheila. Coop and Ava prepare to leave. Jeffrey and Olivia try to deny their feelings.
Reva is walking along when she sees Billy and Sheila pass by flashing the expensive jewelry that he's just given her. They go up to Billy's room and he tells her that he's happy that she's opening up his mouth and ears to so many new things.
Alan-Michael gets off a plane and his new assistant informs him that Ava is leaving today. She asks him if there's anything he wants to send her. 'Yeah, leg irons.' He returns to his room and starts to prepare things. Coop arrives at the door to pick up Ava's last check so that she won't have to. Alan-Michael is disappointed but doesn't let on. He gets his assistant in and rushes through work before he sends her off with an envelope for Ava.
Buzz asks Olivia if it is hard for her to see Ava go. She only hopes that with, Ava gone, things will get better for them without her as a reminder. With Ava is gone, Buzz should hurry up and propose to her, but he reminds her that Jeffrey will still be around. Spotting Coop, Buzz walks over to him to say goodbye and gives him some spending money. He wonders why Coop doesn't seem sadder to be going and Coop only hopes that things will be better for them when they're gone. Olivia wanders back to Towers. As she passes by Ava's room, she glimpses her putting her adopted mother's photo in her luggage and then walks away. Hearing someone in the hall, Ava looks out but Olivia is gone.
Josh and Cassie are under the mistletoe and he wishes it was up all year but she says that they don't need an excuse. She goes to get them drinks when Reva knocks on the door. She bursts in and tells him that she's still worried about Billy and needs his help. Cassie returns with drinks and is startled to see her sister standing there. Reva's concerned that they don't know anything about this Sheila, but, from what she hears, she could be taking Billy for a ride. Josh assures her that it's hard to take Billy for a ride and reminds her that people used to say the same thing about her. She reminds him that what people said was actually true. Josh agrees to help her, even though he thinks she's wrong. She goes out to the car and he tries to explain himself to Cassie. She tells him that it's okay; this is about Billy and the business, not Reva.
In the hallways at Towers, Josh is complaining that Reva always drags him into her mess and she says that, no matter what she does, he never approves of the way she deals with things. As they argue, Billy opens the door and invites them in. Josh gives him a miniature tree and asks him to go get some ice with him for drinks; they want to get to know Sheila better. Alone, Sheila starts to talk all about Billy and Reva is amazed by how well-informed she is. Meanwhile, as Josh and Billy head back to the room, Billy says that he knows Reva dragged him there but she's worried about nothing. He's even investing in Sheila's marketing business he says, as he shows Josh a substantial check. Startled, Josh politely drags Reva out of the room. She's now convinced that Sheila is on the level, but he's convinced that she's up to no good.
Coop calls Ava to remind her how cool it will be to finally have an ocean between her and her parents. She tells him that she's busy and gets off the phone, obviously still having seconds thoughts. Jeffery sits at the bar and she sits down beside him. While she tries to say goodbye, he can only shrug and act cold. She gives him her phone number and a Swiss army knife (which she can't take on the plane). He tells her that he has nothing to give except 'this' and rips up her phone number. Repulsed by his coldness, she leaves and he picks up the knife and sighs sadly. Moments later, Cassie appears and sits beside him while he wallows in self-pity. She asks him what it's like to discover that you have a full grown child. He tells her that she seems nice, but they can't have a relationship and it's for the best. Cassie can tell when he's lying. He insists that he's not into kids, but she reminds him of how good he was with RJ. All the same, Jeffrey doesn't want to get involved in anyone's life until he has his sorted out. Seeing that he's reluctant to speak anymore, she changes the subject and asks him for a favor.
At CO2, Buzz asks Ava not to let Coop get too British. She hugs him and thanks him for everything that he's done for her; he's been like a real father. He tells her that any parent would be happy to have her. Meanwhile, Jeffrey and Olivia run into each other in the hallway outside her room. He tells her that he saw Ava and shows her the knife she gave him after cornering him in a bar. She tries to shut the door in his face; she's furious that he talked to Ava at all. He accuses her of being jealous that Ava actually tracked him down and gave him a gift. She imagines that he's just manipulating Ava by keeping her at arm's length. He apologizes again for hurting her, but her relationship with her daughter is not entirely his fault. He walks over to the trash and drops the knife in before Olivia slams the door. Staring down at it, he can't leave it there and picks it up again. In her room, Olivia sadly looks at a picture of England in the newspaper. Coop has overheard this entire exchange as he went down the hall. He creeps away and returns to Ava's room. She is still packing and he hands her the check from Alan-Michael. She stops a moment to think about how much she enjoyed working there. He tells her again that, once they are gone, he can give her the life she deserves. She starts to worry that they'll be late for their bon voyage party and jumps into the shower. Alan-Michael's assistant arrives with an envelope for Ava and Coop takes it. He opens it and finds that Alan-Michael has offered Ava an executive promotion to replace Dinah. Coop puts it in the garbage.
Cassie returns home to see Josh and Reva still arguing about whether Sheila is up to no good. They bicker until Josh goes outside and screams that Reva is right; Billy is vulnerable and is being victimized. Cassie says that it's true; she just saw Jeffrey and he got her Sheila's rather large criminal record. Reva apologizes for involving them and Josh says that, at least Cassie is involved now, 'so it's not just me and you.'
