For how big a of deal "Gangs of London" has made the Wallace murder out to be, it certainly did little with its murderer. Turns out, maybe that choice was for the better as the real benefactors behind that act are far more compelling than just some guy. The reveal doesn't come without its flaws, notably an unfortunate lack of focus, but it's substantial all the same. Concurrently running with that development are several other big ones that pay off to great effect.
I'm still a little puzzled by how the action set pieces are spaced out. Knowing how Evans prefers to show the profound acts of violence in fight scenes and last time, a torture sequence, I would have assumed that the two set pieces we got in episode seven will be an escalation. They aren't filmed particularly well nor do they highlight the severity of the acts in the moment, only in their aftermath. The first one in particular is difficult to keep up with as the camera's focus keeps shifting, the geography is incomprehensible and the opposing sides aren't clearly lined up. Whether this was story purposes, time or the director's choice is anyone's guess.
On the other hand, the plot and all its other branches get their due. There are plenty of satisfying payoffs. The Albanian sub-plot is finally heating up thanks to some brilliant scenes and the Turkish front is also accelerating to new heights. However, it is beyond debate that the Dumanis and the Wallaces had it the most crushing this time around. It's a reveal with plenty of layers and the good news is, it's a very flexible revelation. Arguably, it took "Gangs of London" a little too long with too many dead ends to get here, but with only two episodes left, the players are in the right place for what looks like a big bang.
