Maybe it's awful timing that Arthur finds them like this. He doesn't want to have to be the one to step in between Eames and the man he so desperately wants dead, but as soon as Arthur sees the man who can only be Gilbert Norrell pinned against the wall, he takes his gun out of its holster and jogs toward them.

"Eames!" he shouts, gun raised but not pointed at Norrell's face just yet. "Eames, put him down!"
