Oi, I am in charge of bell - tolling! And I hear it for Javadi next.
He said something like 'I'm fed up with running', or I choose not to spend my life on the run. He's just had his fingernails pulled out, and had guns printed at his head. He was saved, only to shoot his saviour.
Maybe he is the king, whose move cannot be predicted? But someone else (Dar?) Is the player. Hence Javadi moves out from Saul's protection. And, er, checkmate. Or more probably, bang.
Also, his storyline is over. We know as much as we need to know about the Iranian deal.
