Lois watched him worriedly, for once at a loss for words. "I'm sorry, Clark." And she genuinely meant it. "I know how hard you've worked to keep your identity a secret. I'm -- I'm sorry."
She waited before going on. She had an urge to hug him, hold him until his worries went away, but remained where she was. "Most people love you, just like back home. But it's only the ones that lived on Earth that were vortexed here, the ones on those boards, that know your identity. Other people in this world think Ultraman is a character and his alter ego has a different name too. So you're safe with the majority of the population. ...I'm sorry to be the one to have to tell you this. I don't know any other way to tell you."
