Actually, he was angry at Dani.

Because Malcolm was being tortured, he was moaning because of pain, he couldn't even breathe... But she just stayed hidden, waiting for him to find a solution... I know what you're gonna say : she couldn't do anything.

Not true. She should have walked behind this woman and aimed her with her gun, or made a karate move, just like she did in 1x13 to this woman. But nop. Even her réaction when she saw this scene was insensitive. Malcolm could have died !

Martin was just mad at her. I don't think that he was going to kill her. It's not like the Surgeon. You see... Not the right operational mode. Plus he needed her help to save his son.

But please I'm tired of the no-sense part of this scene...
