Oh, yeah, keep it going! Will Clark get his eyesight back? If so, will he continue to be Superman? Will Lois put two and two together? And if she does, how will she deal with Clark? How will he deal with what he will surely perceive as her pity? Will Clark adjust to being blind or will his frustration boil over into unintended violence? Will he figure out how to use his super-hearing to echo-locate and navigate?
This is a very original premise, and I know I've never seen this angle of "The Eyes Have It" pursued. Please don't stop now, it's just getting really good.
