In this one the forces at work begin to encounter one another. A group of young people at a party fall to their deaths when a temporary hole forms under them. It then closes up. The team comes to investigate. The only explanation is that all kinds of paranormal events seem to have happened in this apartment building. At the center is 6B, the home of an elderly lady who sees an image of her dead husband. Walter believes this is evidence of a vortex between the two universes and if so, where will it be next. It seems that the old lady (a widow) and her husband (who is a widower from the other side) have an emotional connection which facilitates the danger of the vortex. Well thought out episode.
