Despite being unplugged, Betty's telephone somehow manages to receive a radio transmission from the Chinese freighter carrying XIII.
The disconnected plug for Betty's telephone is a standard American modular connector, when the character is supposedly in London, England. British telephones use a "BS6312 431A" plug, completely different to the plug shown in the scene.
The Chinese marine's rifle is a bolt-action (i.e. single shot, not automatic) and does not have a magazine inserted. Despite this, the marine manages to fire three rapid bursts of multiple shots each.
