At 26:05 in Lucy (Charlene Tilton) has a beauty mark/mole on the right side of her bottom lip& her hair is parted with her barrette on the left side of her head (quick glimpse 26:03 in). At 30:10 the mark has moved to the left side of her bottom lip & the barrette is on the right side of her head. It appears 1 of those shots was a mirror image of the other.
The correct quote from Sue Ellen after Afton insults John Ross (by accusing him of being like JR) - "Just so you know Afton, the most despicable thing JR ever did, was you."
