The thug turned to scan the corridor with his gun, his other hand still on Betty's neck. But he didn't even get a chance to say 'who's there'.

That laugh again. The thug jumped to his feet, Betty forgotten for the moment as he turned wildly to get a shot at whoever slugged him, getting angry with himself at being taken by surprise. Betty stayed still, torn between escape and the fear and curiosity of the unknown.
