I see Lois has and interesting decision to make.
She basically has to delete her whole existance, her world and herself, in favor of a potentially better one. And, of course, better is a subjective word.
Does she have it in her to essentially end her life, (because she will become a different person and the Lois that she was/is will be gone), for the sake of a future world that 'appears' brighter? Does she have the right?
One thing I'm pretty sure of... this has to be Lois' decision alone. I don't think she could, or should, burden Clark or anyone else with this moral dilemna. The fate of two worlds will have to hinge on what Lois thinks should be done.
Tank (who wonders if we are closing in on the 'big finish')
