Yeah, with Saul, the Iranian guy and the Israel connection during the season, there must be something there - otherwise there is a bunch of wasted time spent on it. Plus, in the end, Dar Adal has always been a protector of the US over foreign entities.

Yeah, it seemed clear in action and words that he relocated Max. The initial interrogation was for show. As he said to Max, I could have hurt you if I wanted to already. Dar Adal also had told Carrie to stand down a while back and that she didn't know some info.

The Third Party may be Iran…

I suspect he in infiltrating the sock-puppet guy and isn't on the outside as much as it appears. Much like he was on the inside in S3 at the end.

I suspect Dar Adal will turn out to have been running a program to infiltrate the sockpuppet guy to take down the plot to kill the president. He is always on the other side of what you think he is doing.
