Harley follows Gus to Cedars where he says he's there to get a deposition from a nurse. While they two hug, Gus pockets a prescription pad from the counter. After Harley leaves, Gus, it appears, has illegally had a pain killer prescription filled and takes one. Mallet calls him, telling him the two of them have to get to work immediately completing paperwork for the commissioner. Gus tries to beg off but Mallet insists. As Gus gets up to go to the station, he stumbles.
Meanwhile, Mallet has been outside of Company with Dinah where they discuss their vacation plans. Dinah is suspicious of why Harley wants her out of town. Mallet reassures her that she contributed a lot as interim CEO at Spaulding and that Harley is aware of all Dinah did for her. Mallet leaves and Harley shows up. Dinah tries to talk to Harley about her concerns, but Harley, on her cell phone trying to track down Gus, keeps putting her off. Harley learns that Gus was not at Cedars for an interview with the nurse and starts to leave, telling Dinah she can't deal with her right now. Dinah grabs Harley's arm and says, "No, you don't walk away from me." Harley is shocked as Dinah tears into her saying that Harley is the one who needs a break and Dinah will cover for her just as she has always done, every step of the way, just as a corporate doormat should-throwing in the fact that Harley slept with Mallet in her face. While Harley is trying to assure Dinah how much she is valued and how sorry Harley and Mallet are about sleeping together, Harley gets a call from the police station telling her that someone was shot.
Gus goes to the station to do the paperwork. His vision is out of focus and his movements are awkward. As he and Mallet are about to settle into their desk work, a tip comes in that the mechanic for Ross's plane is in town. Mallet insists that he and Gus go confront him. Gus, knowing he is in no shape to go, tries to convince Mallet to go alone and let Gus handle the paperwork. Mallet, oblivious to Gus's condition, insists that Gus go with him. At the stakeout, Mallet tells Gus to stop dozing off, what if they have to chase the guy. Just as Gus is telling Mallet that the guy isn't going to show so they should leave, the mechanic shows up. As Mallet and Gus leave the car and approach the mechanic, the mechanic draws a gun. Mallet yells for Gus to take cover when a shot is fired. Gus, losing his balance against the car door, drops his gun and grabs his chest, sinking to the ground.
Inside Company, Coop confesses to Ava that Lizzie is pregnant. After dropping her tub of dishes, Ava says that Lizzie is lying-that she just wants attention and it's a ploy to hold onto Coop. While Coop admits that could be a possibility, he also notes that she could actually be telling the truth. Coop leaves a message with Lizzie's voicemail to give him a call as he needs some answers. Just then, a representative from Oxford arrives for an interview with Coop that Coop had forgotten about. Coop almost bungles the interview, but Ava intervenes, assuring the rep that Coop lives and breathes for the opportunity to be a part of the Oxford program. When the rep leaves, Coop thanks Ava for bailing him out and tells her that Oxford isn't all he wants. The two kiss.
While Tammy is at the police station having the restraining order against Jonathan dropped (after a mini-lecture from Remy), Jonathan goes to Lizzie's room to confront her about her pregnancy. She admits that she is pregnant but eventually makes it clear that it's Coop's baby and not his. She tells him that she already knew she was pregnant when she slept with Jonathan. After some convincing on Lizzie's part, Jonathan accepts that he is not the father and looks relieved. As he leaves he tells her, "Good luck, you're gonna need it." After he leaves, Lizzie no longer looks so convinced that Coop is definitely the father, but later fantasizes to Roxie the Dog that they will all live happily together in a big house one day-her, Henry, Roxie, and Roxie's new baby brother or sister.
Jon returns to Outskirts to find a tank top and boxer shorts clad Tammy lighting candles and putting on music. She tells him she has done this to celebrate the end of the restraining order. In a symbolic gesture she burns the document and the two celebrate smooth sailing from now on.

He tries to make his way out of the cabin but Harley forces him back inside the cabin. Meanwhile, blaming Gus' troubles with drugs for Mallet's shooting, Alan-Michael suggests to Dinah that they leak this story to the press to oust Harley from Spaulding.

As she considers this, he pulls out a gun which makes her nervous. However, he convinces her to go forward with his scheme. Alan-Michael snaps photos of Harley and Gus from outside the cabin.

After a brief exchange, Tammy and Jonathan go home. At Outskirts, Tammy talks about how weird it is hearing Lizzie talk about becoming a mom.
