Fanfic written between 1995-1999, pretty sure. Lois doesn't know Clark's secret yet. Lex captures her and there's a bomb about to go off and kill her/destroy the building. For whatever reason Clark can't show up as Superman so he comes as Clark and Lois is devastated because she thinks now they will both die. Then, to her surprise, Clark flies them out of building just in time. Then of course he has some explaining to do.

Anyone remember this one?

I don't think I've read that one, but I'd like to!

Yeah, I remember it, but I can't think of the title. Search the Archive themes for "revelation."
I reread it not too long ago.
Good luck
