It seems that the writers are escalating the darker aspect of last week's episode, Prey. Clark is once again faced with the "threat" of going public as Jimmy tries to find out the identity of Metropolis' secret hero. I find it to be getting tiresome that he's so focused on keeping his secret. The revelation that there's a noble hero out there would give us normal people some hope that there is someone in this world who's pure and selfless (as he comes to realize).
It was an interesting touch to have Lois's side story only revealed to us through the mind reading talents of the villain. We were not made aware that she knew who he was (or his past killings) until he touched her and learned of it himself, which is when she turned from the naive damsel in distress into the ruthlessly clever reporter we all know and love. She kicked some meteor-infected ass. But its interesting that out of all the people she could call for help (including the police), she calls her farm boy. Hmm.
