However, shortly after being promoted, Shinwell was found dead in his apartment.
It affects them in very different ways.
Each had a very different relationship with Shinwell as of his passing.
So in the last two episodes of the season, its going to be a point of friction.
It puts Sherlock and Joan in an interesting place as we get into the finale.
Presumably, this is someone within SBK figuring out what Shinwell was ultimately trying to do.
They pickup Shinwells gauntlet and run with it.
SBK always represented the greater evil and he would do virtually anything to see them undone.
Shinwells death changes things.
They lost their greatest wedge into that organization.
At different times this year, theyve left Shinwell to his own devices.
Theyve trusted that between him, with the assistance of the gang unit, SBK will go away.
Going into the finale, a gang war will erupt.
Its a familiar face in that its someone we will meet in the penultimate episode.
Theyre going up against a very different kind of gang leader, to say the least.
Weve talked about SBK all year, but more often than not, it was in general terms.
With Shinwells passing, it was absolutely time to look at the individuals that he was going up against.
He said repeatedly that hes one of the shot callers.
It would certainly appear, as of Sundays episode, that he got too close to someone that powerful.
