With a new step to take if he is to succeed in his mission, Loid sets out to find a woman who is willing to marry him quickly. Franky's suggestion that he could play the wife is rejected, so he brings the files on all unmarried women in Berlint. Anya worries that her presence may cause women to stay away, but Loid reassures her.
Meanwhile, Yor Briar, a clerk at Berlint City Hall, endures the ostracization of her colleagues due to being single at 27. When one of them mentions that a single woman was arrested recently by Ostania's State Security Service, Yor lies that she has a boyfriend and accepts an invitation to a party thrown by her co-worker Camilla. That night, she receives a call from her brother Yuri, who has learned through a friend about Yor's "boyfriend", and another that leads to the reveal that Yor's actual work is as a professional assassin: during this job, the dress she wears has a tear, which she laments because it's the only one she has.
The next day, Loid takes Anya to a dress fitting for the interview, at the same time as Yor comes to request the dressmaker to fix her dress. Loid recognizes her from the files Franky brought, but is more astonished at how he didn't notice she was there until she spoke up. Anya uses her telepathy to learn Yor's secret, and, deciding it would be fun to have her as a mother, "subtly" reveals how much she misses her mom. Yor and Loid speak outside the shop, and agree to try faking a relationship.
The day of the party, however, Loid is called to a side mission to stop several smugglers. Convincing Franky to support him, Loid manages to escape with the target (a box with jewelry) and takes a ring for himself to propose to Yor, but he suffers several injuries in the fighting.
Meanwhile, Yor has been waiting for Loid to arrive, only to believe he won't be coming, and she decides to attend the party in spite of knowing she will stand out for not bringing her supposed boyfriend. Fortunately, Loid arrives before the party is over - only to accidentally proclaim to be Yor's husband. Loid and Yor decide to roll with it, and Loid makes a successful impression of the other guests. Camilla attempts to shame Yor by implying she was once a prostitute, but Loid replies that he would consider her admirable if it were true, causing Yor to realize he could be the man of her life.
As the party ends, Loid and Yor begin to make their way back home, only to be attacked by the smugglers from before. Loid states they are some patients of his, which Yor actually believes. The two fight off the group, and Yor asks if they can continue pretending to be married. Loid agrees, and (having lost the ring from earlier) uses a grenade pin as a ring while they pledge their vows.
Tropes that appear in this episode:
- Alpha Bitch: Yor's co-worker Camilla seems to be the adult version of one, taunting Yor over being single at 27 and then trying to humiliate her when she finds out Yor is supposedly married.
- Because You Were Nice to Me: Yor's face when Loid defends her decision to do distasteful things for the sake of her brother indicates she's starting to develop feelings for him.
- Blatant Lies: When the remains of the smuggling ring attack Twilight as revenge for disrupting their operations Loid quickly states that they are dissatisfied patients of his, and then later claims that beating them up is good for the recovery process. Yor believes all of these lies much to Loid's confusion. Even after the grenade.
- Brick Joke: Yor's coworkers mention that someone broke into city hall, but only took information regarding girls. Loid's next segment reveals that it was Franky who did this to help Twilight find a suitable fake wife.
- Bowdlerise: In the original manga panel, body parts are clearly sent flying when the grenade explodes. In this adaptation, only a burned piece of cloth floats away from the blast.
- Casual Danger Dialogue: Loid and Yor discuss becoming a married couple for the sake of both their interests whilst casually kicking the asses of Loid's "patients" (actually the smuggling ring he foiled earlier in the episode).
- Conveniently an Orphan: Yor is an adult but qualifies, as with both her parents dead and with her brother regularly abroad for work allows her to more easily have a double life as an assassin.
- Face Fault: When Yor and Loid are running from the alley, she casually asks him if he would marry her. He falls flat on his face out of shock.
- Fake Relationship: Yor tries to get one so she can have a date for Camilla's party and let her brother Yuri know that she has someone to take care of her. This lines up with Loid who still needs a fake wife for his mission and initially asks her to help him afterwards by pretending to be Anya's mother for the interview. After inadvertently calling her his wife at the party Loid and Yor decide to pretend to be husband and wife for the foreseeable future to help their interests.
- I Did What I Had to Do: Discussed at the party. After Loid arrives from a long shift at the hospital and explains that his injuries are from a mental patient who had a psychotic episode (he was actually shot at by a group of jewel smugglers whose operations he was ordered to stop), he introduces himself as Yor's husband. When Camilla gets jealous that Yor's husband is more handsome than her boyfriend, Camilla tells Loid that while Yor's current job maybe a clerk at City Hall, she used to work as a private on call "masseuse", with the heavy implication that she was a prostitute. While Yor clarifies that she used to work as an on-call acupuncture specialist, she admits to herself that the work was a cover to get close to her assassination targets, but when she tries to explain herself to Loid, he states that he doesn't care, and even admits that is admirable, since she and her brother have been orphans from a young age, he admires her dedication to having to do anything, including sacrificing herself, so that she and her brother could survive during such harsh times.
- If Only You Knew: Loid praises Yor for being willing to do anything, no matter what sacrifices it required on her part, to look after her brother, after Camilla implied that she used to moonlight as a prostitute. In actual fact, when she was being sent to hotel rooms to meet with rich men it was so she could kill them, but the same principle applies and Yor is extremely touched by his words. Ironically, Loid himself wasn't thinking of anything as mild as a bit of sex work when he spoke, instead recalling all the times he's dirtied his hands with cloak-and-dagger activities to protect the peace.
- It Amused Me: Anya discovers that Yor is an assassin by reading her mind, but she doesn't inform Loid of this only because she thinks having an assassin as her mother is exciting.
- Laser-Guided Karma: Camilla gets this in spades after inviting Yor to the party just to humiliate her and promising to tell her brother that she came there alone. Firstly Loid shows up and calls himself Yor's husband, derailing her plans to humiliate Yor, then she gets scalded by some food that she had "tripped" and thrown at Yor to scald her. Finally, when she insinuates to Loid that Yor was a prostitute, he just says that doing something distasteful to help someone you love is an admirable quality and leaves, making Camilla look petty.
- The Matchmaker: After reading Yor's mind and finding out that she is an assassin Anya decides that it would be cool if her parents were an assassin and a spy. She then proceeds to put on a performance about how sad she is that she doesn't have a mother when it looks like the two are going to pass each other by.
- Murder Is the Best Solution: Yor considers murdering every adult at the party so Yuri won't find out she was lying about having a boyfriend, but decides not to because there are kids in attendance as well, and Loid ends up arriving late a short time later from his job at the mental hospital (actually a mission to stop a gang of jewel smugglers).
- Murder the Hypotenuse: Discussed by Yor at the seamstress' shop. When Yor sees Loid she thinks about asking him to pretend to be her boyfriend for the party that evening, but when Anya comes out from being measured, she deduces that he's married, and fears his wife would kill her for flirting with her husband. However, Yor already told her coworkers she was bringing a boyfriend, so she comes up with the idea to kill his wife, but decides not to because that would create other problems. In the end the situation gets resolved when Anya reads their thoughts and since Loid needs a wife (for the school's interview) and Yor needs a boyfriend, Anya decides that having a spy for a father and an assassin for a mother was too much excitement to pass up, so she sings a song about being so lonely for not having a mother, so they make an agreement to play a loving couple.
- Noiseless Walker: Yor's training as an assassin means that she is able to slip past Loid when she arrives at the tailor. Loid is taken aback that anyone could sneak up on him like that.
- Obfuscating Stupidity: At one point, Loid gets confused about if Yor is really very sharp or very dumb. The truth is that she's more Super Gullible and thinks in odd ways.
- Old Maid: Yor starts as single 27-year-old woman desperately trying to find a man who's willing to be in a Fake Relationship with her. This is justified, however, because in the universe of Spy X Family, an unmarried 27-year-old woman draws the scrutiny of the Secret Police, and that's the last thing an assassin needs.
- Plot-Based Photograph Obfuscation: When Yor calls Yuri we see a photo of them on the table but his face is blocked by the curly telephone cable.
- Second Episode Introduction: Yor.
- Slut-Shaming: Camilla reveals that, before she got her office job, Yor used to visit men at hotels to perform "massages" (in actuality, Yor's cover for sneaking out and performing assassinations) in order to humiliate her. It backfires as Loid states that the fact Yor was willing to do something unpleasant like that to support her brother shows true resolve and is actually an admirable quality in a person.
- Stating the Simple Solution: While helping Loid go through a list of potential marriage candidates, Franky wonders why he doesn't just call up a female agent from his organization to play the part. Loid explains that recent spy hunts have thinned their numbers and the remaining agents are currently stretched too thin to provide support at this point.
- Wacky Marriage Proposal: Yor suggests giving their marriage a chance while they are running away from Loid's "patients", and Loid agrees by using a grenade pin as a makeshift ring (and blowing said "patients" with the grenade at the same time).
- Wouldn't Hurt a Child: Implied with Yor. After being subjected to the humiliation of showing up to Camilla's party without a date and Camilla telling her she'll make sure to tell Yuri that, for some seconds Yor seems to consider murdering every adult at the party to avoid being humiliated further, something that is earlier established Yor could easily pull off. But barely a second later, she shakes her head and doesn't go through with it, and moreover glances around at the children and their parents before thinking that this must be "normal".
