Charmed (1998) - 2 mistakes in "Thank You for Not Morphing"

Plot hole: After the shapeshifter turned from a mailman into Andy, Prue told him about her father returning to town. Later, the real Andy came to the house, and then after a cut, he and Prue were talking about Prue's father, Victor. Andy has known Prue since high school, and therefore knows that Victor has been gone for twenty years. And since Prue only told the shapeshifter about Victor's return, the real Andy didn't know about it. So how could he and Prue have gotten onto the subject of Victor being in San Francisco, a fact that surely would have surprised the real Andy, without Prue figuring out that Andy wasn't the one she talked to earlier that day?

Visible crew/equipment: In the scene where Prue comes home and finds Andy inside the manor. There is a shot where if you look behind Andy's shoulder you can see half of the body of the director in the background in the observatory room sitting in a director's chair.
