Summary
Loid leans in to kiss Yor, which leads her to panic slightly. Yor decides to down a bottle of wine to help calm her nerves. Loid whispers to her that they don't have to do this, which leads Yuri to question why they are whispering and whether they will actually kiss or not. Yor throws a fork at Yuri and then leans forward to kiss Loid, telling him to close his eyes. As Yuri watches this, he flashes back to his past with Yor raising him and him wanting to marry her. Unable to watch Yor kiss another man in front of him, Yuri decides to jump in between the couple to stop them. A now embarrassed Yor decides to slap Loid, but ends up slapping Yuri instead. He flies across the room, waking up Anya momentarily before she returns to sleep. Yuri gets up with a bloody face and misinterprets the slap as Yor being mad that he tried to stop their kiss.

Yuri concedes defeat for now but being drunk and having lost some blood he has trouble keeping his balance. Yor asks if he needs a taxi and takes him on her shoulder so he can regain his balance. Yor, who is also drunk, has trouble balancing as well is caught by Loid who holds them both up. He grins at the two of them and tells them how much he admires how wonderful of siblings they are. Loid thanks Yuri for all the work he has done to protect and support his sister and assures him that he will do everything he can to support her as well. Yuri, embarrassed, slaps away the hand Loid was using to hold him up and announces he is going home. Loid tells him that he is welcome to come back and visit anytime for Yor and meet their daughter Anya. Yor tells him that Anya tried to stay up for him but ended up falling asleep. Yuri announces he will come back to prove that Loid tricked her into this marriage. Yuri gives Loid a warning that if he makes Yor cry he will have him executed but cuts off before saying the executed part. Yuri then rushes off as Yor wishes him a safe trip home. Loid wears a deadpan expression, thinking about how Yuri almost threatened to have him executed.

Loid proceeds to search the apartment to make sure that Yuri did not plant any listening devices, to which his search turns up nothing. Yor thanks Loid for tonight and how he was willing to accept Yuri as family. Loid comments how he envies the two of them as someone who does not have any other family apart from Anya. Most of all though, he was just glad that Yuri did not find out that their marriage is a sham. Yor comments that she just wants to go to bed to which they remember the shared love bed they had set up for Yuri's visit and say they will sleep separately. Anya and Yor sleep, while Loid reads an issue of the Spy Wars comics. He contemplates when the last time he felt envious of someone was before deciding to head to sleep. He thinks about how tomorrow he will have more quality time before pausing and then thinking about his mission. As Yuri heads home, he asks two men which direction the station is in. Shocked by his bloody appearance, they tell him to go to the hospital.
