I've scrolled through the files by title, and used Google search, but can't find the fic I'm thinking of.
Perry and Jimmy join Lois and Clark at the brownstone for coffee after work, and Clark has to reveal himself to save them from a bomb under the coffee table he doesn't hear right away. They wake up the next day in Ellen's spare bedroom, and Clark has to talk to Perry and Jimmy to help them adjust.
Ring any bells?
