AnnieBHi!
I have to admit that the part of this story that most intrigues me is the part with Lex. He seems to have changed (but I can sympathize with the desire to be able to walk around without a special suit).
Metal X and Kryptonite ... hmm. For a minute there, I thought you might have Dr. Klein wait to test it on someone other than Lois or Clark (like maybe Zod).
Everyone has noted the change in Lex, but there is more to come in that regard. Especially with Aykira Milan around.
Metal X will come into its own very soon.
