Brother Mouzone killed Notorious BIG. And his first name is Clarence.Because this sketch◊ of BIG's assassin is too similar to Mouzone for coincidence. Also, in Homicide: A Year on the Killing Streets, after a riot takes place at Maryland Pen on Forrest Street which results in numerous serious assaults on correctional officers (which, being high-profile cases, the section has to investigate), the detectives flick through the names of their interviewees and name them; one is "Clarence Mouzone", described as "a crazy bastard" who beat three murders before they could nail him. Sounds about right!
David Simon exists in The Wire universe, but we never see himIn the show's universe, he's just a police reporter for The Sun who hasn't gotten into television yet. Hell, if Jay Landsman is a cop in-universe and out of universe and The Sun is Baltimore's main newspaper in both realities, why not? One major difference: in The Wire, David Simon is a buff, chiseled sex god who rides a motorcycle and works as a bounty hunter on the side. Because, y'know...when you're the creator of the show, you can do whatever you want.
Levy deliberately leaked Marlo's phone numberIn Season 5, Maurice Levy obtains Marlo's phone number and very deliberately places it in his rolodex, right in front of a former policeman with a history in wiretap investigations, very carefully using the words "wiretap investigation". It seems unthinkable that the amazingly calculating Levy would do this without a purpose. Did he deliberately plant the idea in Herc's head to leak the number to his former colleagues, to create a profitable wiretap case as soon as possible? Hell, did he even figure that with the police (very publicly) so short of money right now, that the investigation would be shoddy and easier to win than most? And if he did, is he the finest chessmaster in Baltimore? It seems likely.
George Pelecanos uses the tears produced by the episodes he writes to fuel a genesis deviceHow many gallons of tears has he gathered over the years? Wallace's death, Sobotka's death, the end of Hamsterdam, all the kids in season four except for Namond getting their futures ruined, Michael losing his soul in season 5... it all adds up to a diabolical scheme for world domination.
Marlo Stanfield was molested as a child.Possibly by the same culprit as Chris. The two seem to have a unique, unspoken bond and absolute trust between them (Chris stands guard while Marlo busts a nut). Chris and Michael are the other two characters on the show who are quiet and introverted, as well as terrifying individuals and ruthless killers. Both molested. And Marlo immediately seems to take a liking to Michael. Consider Marlo's shooting of the girl in Season 3, in which he puts a bullet in each tit and another in her mouth. On top of that, just watch his reaction to the rumor that he's gay, and maybe contrast it with Michael's outburst in which he accuses Cutty of the same, claiming "everybody's too damn friendly." A mindset like that could definitely lead to a personality like Marlo.
Marlo won't retire, so in the end everyone goes to jailIn the final episode there is a scene where the prosecution and the defense make a deal. Basically they both have to agree to the deal or they and everyone else will go to jail for the various crimes they commited. One of the stipulations is that Marlo retire. In the final montage Marlo gets bored with legitimate business and goes back to the street. So all the other happy people in the montage wind up going to jail because of the chain reaction set up earlier
Spiros is the Greek's sonThe Greek seems to have a close, almost fatherly relationship with Spiros, and he is old enough to be his father: when the Greek dies, Spiros will take over the organization.
