The 12th episode, Cleaning Up, is when Levy basically tells Stringer & Avon to kill the security lady and anyone else that can hurt them. She gets killed not too long after. Wee-Bey should have been in Philly by then, so who killed her?
Have another theory.
In that episode they edit it so that Wallace's demise is shown
right before a scene where Daniels/Mcnulty are seen trying to find him and prevent it.
I think they edited an earlier part of the episode in a similar way.
The stripper who wears The Wire is shown sitting in the makeup/mirror area next to Avon's office, trying to capture audio.
Sitting next to her is another stripper.
Two Baltimore goons are shown next them. One of them tries to compliment and pick up the other hooker. She tells him to get his money up, first.
His words "That's why we're here. To talk about a package"
Avon opens the door, before the goons go in, the guy says to stripper, "yeah, I'm a hook you up with some uncut".
Cops raided Avon's stashes the episode right before that, so when I first watched that episode, I thought they were ,or represented ,a new connect. But I think they were random hitters that Avon contracted out to hit the security lady. No connection to his organization, and paid them off afterwards with a package of drugs.
Those guys appear on screen, are shown being lead into Avon's office.....next scene is the security lady's body
