So I haven't seen the show. But Clark took a bullet in his chest because he threw himself in front of Lois, who would have been hit and quite possibly killed if he hadn't. If Lois had figured out his secret then and there, would she really have been furious enough to spill his secret to the gang, or to anyone else for that matter? Would she have thought - or would her subconscious mind have concluded - that he was enough of a louse to be outed to the world? Even though he kept saving a lot of people, particularly her, all the time?
