Great conclusion to a great trilogy, CC. The way Lois was testing Clark is very reminiscent of the movie, Superman II, when Lois throws herself in the river, absolutely certain Clark will turn into Superman to save her. I can absolutely see Lois throwing herself in a shark tank just to see what Clark will do.
Fortunately, she didn't have to.
I like the way Clark tries to drop hints, but is too scared to come right out and say, "I am Superman." But as it turns out, he didn't need to for her to find out.
My favorite part is when Lois says that she believes whatever he tells her is true. Until he says he's Superman, she tells him that she still "doesn't know."
The only problem I have is that I am uncertain if Clark would ever invade her privacy the way he did. He might accidentally see something that's left out, but I can't see him breaking into her place to look at something he absolutely knows is private.
Superb story. Look forward to your next endeavor.
