Good chapter, although I'm not sure Karen would kick Pam's ass if Pam hurt Jim.  More likely, Karen would laugh her ass off.  Woman scorned, and all that.

I especially like the Ryan/Kelly dynamic in this chapter (Bastard!) - that's pretty funny, and kind of likely. 

I really enjoyed this story a lot. You did all of the characters justice, made them all sympathetic. Which is how I see them as wel, but it's a rare fic that manages to get all the voices so perfect and construct a plot that treats them all fairly. Nicely done!
