Basically, Smith has dealings with the Russians. He also owes Yann a buttload of money. He meets with Viktor, a Russian who wants Smith to do him a favor in exchange for money to pay off Yann.
Next scene is Mireille walking into Smith's office. She says Viktor just showed her pics of John with a dead girl in a hotel room, and she wants an explanation.
Smith says it's how he met John: it was years ago, before Mireille met John, and the girl OD'ed while she and John were getting high. John's dad hired Smith to cover it up. Smith gave those pictures to Viktor to use as blackmail material, to get Mireille to do what he wants. Mireille is pissed, and slaps him, says she could kill him for selling John out to the Russians. Smith says he'll make it go away if Mireille just does as she's told and acts as a courier for Viktor.
It's mentioned that Mireille has only known John for nine months.
Next scene is at Mireille's apartment. She's injured from some sort of scuffle. Smith shows up while she's cleaning up. He's upset with her for killing someone (I think his buddy Bruce, but I can't be sure from the little bits they've given here). Mireille is pissed, she shoves him against the wall and puts a knife to his throat. They argue about the job.
Kirika is in Mireille's apartment, sneaking around and listening. It's implied that Mireille is keeping her a secret from Smith.
Anyway, Mireille gives Smith some microfilm that she got during the exchange that they're fighting about. She asks him if he's seen John, since she left him while he was tripping on acid to make the exchange. They mention that Mireille still has to deliver something to Viktor; Smith says to give him some time. She says she wants John's file, and all of the pics and negatives of John with that dead girl, in return for making the delivery. Smith agrees and leaves.
Mireille meets Viktor, who refuses to give her the pics of John and threatens to keep blackmailing them both. Of course, Mireille kills him.
Next scene is Mireille's apartment again. Smith shows up to give Mireille all of the incriminating files on John. She tells him she killed Viktor, and he gets angry. He says he spent two years setting up his cover, getting Viktor to trust him, and now he has to do it all over again with a new KGB contact. Mireille doesn't give a fuck.
Smith makes a remark about what John would do if he knew Mireille was the assassin Noir. This angers Mireille; she grabs him by the junk, takes his gun and points it at him. She says that if he ever tells John about this, she'll kill him.
Mireille says that she really, truly loves John and just wants to settle down with him. Mireille says that as far as the world is concerned, Noir is now retired.
