Recap: The manhunt is on for the wrongly incarcerated Jaime...and a small army of police officers are chasing after her in a wooded area with bloodhounds. A helicopter is attempting to track her by air - but the bemused pilot gives up and radios back to mission control that the target appears to be "running too fast to be human". The chasing sequence goes on for what seems like a looooooong time, as Jaime bionically jogs through the woods, falls down, then gets up and continues fleeing. Dun dun dun dun dun...
Over in D.C., Lisa arrives at the federal testing lab to deliver Rudy's last existing supply of adrenalizine - but not before pocketing a big wad of the silly putty drug for her own personal use.
Jaime slides down a ravine, falls into quicksand - but quickly pulls herself out - then bionically pushes a giant tree across the quicksand so she can use it as a bridge to reach safer ground. Minutes later, the police arrive at the ravine, but get delayed in pursuing Jaime when one of the officers falls into the quicksand, flaps around helplessly, and has to be rescued.
The prison warden calls Oscar to inform him that [the woman he thinks is] Lisa has escaped his custody...and that he's worried about how squirrellier-than-usual she's been acting lately. He says she keeps insisting she's Jaime Sommers and that she's very convincing.
Lisa delivers a small wad of adrenalizine to the creepy technician at the federal testing lab. He smarmily tells her she's the prettiest courier he's ever seen and flirtily asks for her phone number so he can invite her to dinner, but she turns him down flat and sashays out of his office.
Lisa is driving around D.C., thinking about how much nicer Jaime's apartment is than her tiny prison cell. She smiles while having audio flashbacks of Dr. Courtney saying, "You are Jaime Sommers" - but then contorts her face into a troubled expression when she has video flashbacks of Papa Austin's kind face and the students at the base school.
Jaime bionically jogs out of the woods and finds herself in an industrial area. She spots a phone box, bionically breaks into it, and calls Oscar. She tells him the bizarre story about how she somehow ended up in Lisa Galloway's prison cell. On the other end, Rudy is listening in...and he and Oscar nod knowingly at each other 'cause they both assume that the caller is Lisa Galloway pretending to be Jaime.
Lisa calls Dr. Courtney and tells him she's really really enjoying assuming Jaime's identity and would like to keep that going indefinitely - but he tells her she can't 'cause eventually someone is going to twig onto the truth and blow apart their crazy scheme. He assures her that when he sells adrenalizine to the shady buyers he's lined up, she'll be richer than she ever dreamed - $10 million! - but Lisa makes a meh face and tells him she just discovered that there are other kinds of happiness besides having gobs of money.
Jaime gives Oscar her location, and he promises to send his men right over. He then gets on the horn with the state police and tells them he knows exactly where they can find Lisa Galloway.
Lisa ambles along a city street, dreamily smiling to herself while a song about a new day, forget about the past plays in the background. Subtle, writers. She then boards a California bound plane and continues to smile dreamily.
The state police arrive at Jaime's location...and she looks relieved to see them until she spots Dr. Harkens and the prison warden among the police posse. She looks alarmed and insists that she really is Jaime Sommers...and when the warden coaxes her to peacefully surrender, she flees into a nearby utility building/shed thing and blocks the entrance with giant crates. A man wearing overalls, who's been working inside the building while somehow oblivious to the half a dozen police cruisers that barreled over with sirens blaring, stares at Jaime in shocked bewilderment. Jaime yells out the window that she wants to talk to Oscar Goldman, then looks over at Overalls and says she has a hostage. The warden throws in the towel on anymore coaxing and tells the police they're going to have to call Oscar to help sort this mess out.
Lisa lands in Ojai, takes a small bite of adrenalizine, and continues to smile dreamily.
Oscar arrives in the industrial area by helicopter and gets on a blowhorn to talk to the woman he assumes is Lisa. When Jaime yells from inside the building that it's really her, Oscar tells her she's not Jaime Sommers, and that she's confused in the head. To speed up this 'identity mixup' two-parter, Jaime asks Oscar to whisper a question - no doubt so she can demonstrate her bionic abilities when responding - and instead of asking something that only Jaime would know, he quietly murmurs, "Who are you? What is your name?" and Jaime's voice cracks when she replies, "I'm Jaime." She then appears in the window to stare at him beseechingly, and Oscar decides he's convinced and runs over to the building crying, "Jaimmmmeeee!" and Jaime bursts out of the building so the two can share an emotional hug.
At the Ojai airport, Lisa is greeted by Mama and Papa Austin, who I guess she called in advance to pick her up. She smiles at them and gushes, "It's so good to be home!"
Dr. Harkens and whoever else was in on the Lisa/Jaime switcheroo are arrested after confessing that they were paid off by the creepy Dr. Courtney. Oscar wonders aloud how Lisa was able to pass herself off as bionic during the routine test...then mulls it over for a few seconds and goes, "Oh no! The adrenalizine!" and correctly assumes that Lisa must have taken some doses of it. Jaime scrunches her face in confusion and asks where Lisa is at the moment, and Oscar unhelpfully says he has no earthly idea.
Mama Austin serves dinner, while Papa Austin fetches his Polaroid camera so the three can take a group shot together...and then later in her apartment, Lisa gazes at the photo and kisses it goodnight. She gasps in pain from a sudden stomach cramp, no doubt from all the silly putty adrenalizine she's been taking. After a few seconds, the pain subsides and she's able to drift off to sleep.
Now that Jaime has reclaimed her rightful identity, Rudy shows her his lab rat Plato...and then Oscar comes over to inform them that Lisa only delivered ten grams of adrenalizine to the federal lab, which means she probably gave the other forty grams to Dr. Courtney. Oscar shakes his head solemnly and says that the silly putty is worth a fortune on the open market, then looks even more solemn while adding, "The military implications are frightening, potentially devastating." LOL - indeed it would be scary for the U.S. military to encounter an army of superhuman soldiers whose superhuman strength expires at the end of every thirty minutes per one adrenalizine dose. Rudy, Jaime, and Oscar chew on that disturbing notion while they watch Plato speed-run on his little mouse wheel.
Lisa is making herself breakfast in Jaime's apartment when she suddenly decides to double-cross Dr. Courtney. She calls the D.C. police, reports his exact whereabouts - a motel room in Arlington - and specifies that the OSI would be particularly interested in finding him. She then doubles over with another bout of painful stomach cramps.
Oscar tells Rudy and Jaime that they just got an anonymous tip about where Dr. Courtney is holed up, and says that Lisa is probably with him. While that's happening, Plato suddenly gets ill, looks like he's struggling to stand up, then keels over. RIP, Plato.
Lisa is teaching class at the base school, scarfing down more adrenalizine so she can needlessly write quiz questions rapidly fast on the blackboard. She suffers from stomach cramps again, then sits at her desk and looks tired.
Oscar, Jaime, Rudy, and a tactical OSI team burst into Dr. Courtney's motel room. Oscar demands to know where the adrenalizine is, and a perplexed Dr. Courtney looks over at Jaime and snarks that he should ask her, 'cause clearly she's gone into business for herself. Jaime tells him she's the real Jaime Sommers - but he doesn't believe her and talks about the phone call he had with her (meaning Lisa) yesterday, when he wished her luck while assuming Jaime's identity in Ojai. As the agents handcuff him and march him out of the motel room, Jaime asks Oscar if it's really possible that Lisa went back to Ojai, and he's just like, "I dunno" and shrugs cluelessly.
Lisa is hanging at the Austin house while Mama Austin makes breakfast. Lisa doubles over from the stomach cramping, and an alarmed Mama Austin urges her to lay down on the couch. A few seconds later, the phone rings...and Oscar instructs Mama Austin to just reply yes or no to his questions as not to arouse suspicion, then asks if "Jaime" is with her. She says, "Yes" ... so then Oscar tells her to remain calm while he puts the real Jaime on the line. Jaime explains to Mama Austin that the woman napping on her couch is her evil doppelganger, and that she needs to continue with the charade of believing she's Jaime until she and Oscar can get to Ojai and deal with the situation - in lieu of sending in local police to swiftly remove the imposter criminal from the Austin property so that Jaime's beloved guardian isn't kept in harm's way any longer than necessary.
Rudy shows Oscar and Jaime the lifeless body of Plato, declares adrenalizine poisonous [nice R&D work, Rudy], and says that Lisa will likely meet the same fate if they don't get her to a hospital asap.
Lisa continues to have stomach cramps and is now weeping from the pain. Mama Austin suggests she call a doctor, but Lisa says she just needs rest, then gets up and wanders off to Jaime's apartment in the carriage house.
Jaime, Rudy, and Oscar arrive in Ojai (on what must have been a super fast jet), and Rudy warns that the poisonous effects of the adrenalizine might cause Lisa to act erratically.
Lisa stares longingly at the Polaroid photo of herself and the Austins. She carefully adds it to Jaime's scrapbook as she chows down on more adrenalizine.
Mama Austin greets Jaime, Rudy, and Oscar when they arrive at her house, then worriedly tells them that Jaime's doppelganger appears to be very ill. Oscar orders his OSI team to surround the property, then gives Jaime the green light to go in alone for a poignant one-on-one scene with herself...I mean Lisa.
Jaime finds Lisa sitting at her kitchen table, eating more of the silly putty drug and staring sadly at the photos in the scrapbook. Lisa looks up at Jaime, scrunches her face confusedly, and asks her who she is...and Jaime says she's someone who can help, and that she should prolly not eat any more of the adrenalizine, 'cause it turns out the pink stuff is poisonous. Lisa gets rattled, threatens to kill her, then breaks the kitchen table and whips the broken part of it across the room. Jaime implores her to stop throwing stuff so she can help her - but Lisa says she'd prefer to get help from Mama and Papa Austin 'cause they truly love her, then cries, "Nobody ever looooooved Lisa!" She throws a lamp at Jaime, who breaks the news that Rudy's lab rat Plato died as a result of consuming adrenalizine - but Lisa ignores her and continues to pick up and throw large pieces of furniture in her direction. When Jaime calmly tells her she's being slowly poisoned by the adrenalizine and therefore needs to be rushed to the nearest hospital asap, Lisa finally breaks down and falls to her knees, lapses back into her southern drawl, and cries about how much she hates her life. Jaime coos, "You can change that" and says she'd be happy to help her with that paradigm shift...and Lisa weeps and hugs Jaime's torso.
Jaime visits Lisa in the hospital, and she's doing better now that every remaining scrap of the poisonous adrenalizine has been pumped out of her system...plus, she's happily working on her new needlepoint craft: a gift from Jaime. Lisa apologizes for all the trouble she's caused her during this nailbiting two-parter, and Jaime accepts her apology, then pulls out the photo of "original Lisa" (blech) and says now that she's starting to like herself more on the inside, it's time she underwent that long overdue plastic surgery reversal so she can go back to looking like her real self on the outside...and not be tempted to steal her identity a third time. Lisa says she's totes open to going back to being herself: an illiterate, chain smoking convict who's sure to get extra years added to her prison sentence for the ill-fated identity switcheroo/escape plot.
