And if I'm remembering correctly, VG said at the start of her "story" that she was telling them this because Amber was their (the twins), friends, and she wanted her thoughts on the rumor. She knew Theresa didn't know them. But how else would VG approach Amber if it wasn't thru a friend of a friend. So maybe they should switch the direction of this dumb plot and place the blame on Amber where it belongs.
The whole desperate attempt at a storyline and the hopes VG would have brought it more viewers is so damn stupid. But like you said, the following of the pattern that its ALL Teresa's fault is so predictable and SO old.
