It's not totally clear what's happening yet, but since Clark was in Malaysia the night the special aired and his parents taped it for him, it makes sense that Superman is still around.
As far as where Lois is and what she's doing, it makes sense to me that Superman did come to her and tell her the secret, but that neither of them could figure out how to bring Clark Kent back from the dead. Because Lois finally admitted that she loved Clark, and because there was no way for her to be with him in Metropolis, she's been traveling around the country, waiting for him to be with her when he can. At least, that's what I'm coming up with now. And I've been wrong before.
But if this is what's going on, this is so very sad! Clark can't be with Lois as himself or as Superman, nor can Lois work with the people she came to regard as her second family or at the place where she won such acclaim and had so much promise.
And that would be as terrible a tragedy as the other scenario I'm envisioning: Lois knows that Clark is alive, but can't countenance not being with Clark unless he's really Clark and not using some other fake identity. And she can't be Superman's girlfriend for so many obvious (to us, anyway) reasons, so they're both alone except for the times when the longing just gets to be too much for one of them (like this night, maybe?).
Like I said, I could be wrong. This is probably worse than I've described here. Okay, go ahead, wrench my heart in an awful manner. I only hope I'll survive.
