One thing I was thinking its totally posible that Pam might go over the edge and decide to kill Donna, that would sort the situation out.
Other then that, I can't see where this is going because I can't see Eric falling out of love with her simply because her skin looks like leather, her hair has snot green highlights and her teeth are brown. He is the kind of man that once he has chosen his path to disaster, he stays the road.
Remember back when the entire family talked him out of marrying Sheila and left the church only to find that Sheila showed up afterward and convinced him to go ahead and marry her?
The one I am disgusted with now is Nick, flirting with Katie AND sleeping with Bridget at the same time.
