Barovsky and the Iranians..
When Jax and the gang are planning to do a run down to the Port and roust the Iranians over them messing up Lyla, Nero tells them that b4 they go in there, they better check with Barovsky firt , in case they are working for him.
they all agree.
Then they go down and hit the Iranians first anyway.
And what then brought Barovskys cops in on them so fast?the gunshots?
It was almost nothing from when the shooting began, to when Barovsky's Port cops kicked the door in..
