There's a lot going on in this chapter, and I wonder if all the pieces will find a place in the final puzzle, e.g. the murder-suicide episode: right now I can't see the connection with the rest of the story (but maybe it's just me).
P.S.: Dear Clark, if you don't resolve quickly to tell Lois about your "other self", it'll blow in your face... And that will hurt. :-\
The murder-suicide isn't part of the overall story. It's just a look into their daily work life.
Clark says he's still too scared to tell Lois about his double life. And then he went and hid behind the couch.
