After what was a slightly comedic break from the norm in last week's episode, it's back to business as usual for the detectives as Mulder and Scully are sent to investigate the murder of a city official, which it seems no human could have committed. Scully also has to deal with a personal tragedy, which brings forth many old feelings about the child she once gave away for adoption. All this talk of William - we're going to be PISSED if we don't get to meet this son of theirs again by series end.
