Dandello,
I don't know how you keep knocking me off course. I kept thinking this is it - this time Lois and/or Clark are going to figure out where Superman is, but they don't. And yet, it's completely believable that they don't.
I have to say as soon as I read that Superman left a letter for Lois, I had this very funny image in my head where Lois is reading a letter from Clark telling her he's Superman (or in this case, vice versa) and Clark is standing right there but has no idea.
But back to what actually happened... I love Lex in this. Well, I mean, I hate him, but he's so well written. His controlled fury at Lois is so in-character and his furious glances at Clark just crack me up.
And I can't wait to see Lois and Clark start digging around. Especially without superpowers to help them.
