Walk me through your thought process though. I was shocked the moment he shot her in the head because I thought he shot her because she was shouting at him and it was so out of character.

I am just baffled that someone managed to figure out that he was being mind-controlled straightaway. Especially when the SIM cards could have done any number of things like explode or whatever.

Don't you remember earlier in the film, how they talked about situations where entire camps of people were seemingly destroyed from everyone going to a rage like trance. When they are discussing the original Lancelot's assignment. 

Yeah but I didn't immediately think that that's what's happening to Harry.

In any case, I really enjoyed this movie mostly because of the action. Harry was the movie for me. Without him, it felt much weaker.
