Continuity mistake: Leo says that Piper's past lover is his past life. If it was a past life, in 1924, that means Leo must have died almost straight away to be old enough to qualify as a doctor in WW2. And it wouldn't be his past life but his own past if it was the same life from before he became a Whitelighter. But then he'd also have been 15-20 years older before he died in WW2.
Continuity mistake: After Prue and Phoebe send contagious Piper back up to bed, it cuts to three consecutive shots of buses arriving at camp. In the first shot, the bus license plate is white with the number "2IAB345" and we see markings on the bus as the counselor exits. The second closer shot shows two kids exiting the bus. Then in the third wideshot, with those same two kids beside the door, the license plate is now blue with the number "876QPD" and we see the same markings on the bus as in the first shot, so we know it's the same bus. (00:22:05)
Continuity mistake: When Prue shows her sisters the article in 415 Magazine with her photo credit, in the closeup we see that Prue opens the magazine with the article and Maggie's photograph on the page to the right, but in the next shot facing Piper and Phoebe the magazine is folded open and they're looking at the page to the left with an entirely different page to the right. (00:40:40)
Continuity mistake: When the ani-men break into the manor the entire large center glass of the left door ends up broken, but later while Phoebe is looking for the hydrogen peroxide, Prue notices the front doors and the left door's center glass is intact with only the bottom corner broken.

Continuity mistake: When Leo comes to the manor to tell Piper about Masselin, during the conversation Prue is not wearing her choker in the shots facing her (with her arms crossed) and Phoebe, but in the next shot when Leo tells Piper that he knows she's upset we see Prue's choker suddenly around her neck. (00:11:50)
Continuity mistake: When Prue leaves Buckland's, she's wearing a red tank top, but when she arrives at Camp Skylark, her shirt is different, both in style and color. She can't have stopped to change, because it's mentioned she left the auction house and headed directly to the camp. (00:07:00 - 00:09:20)
Continuity mistake: When Prue is sitting at home bored, she spots the vase with the flowers. In one shot the vase is on the left, and in the next shot it's on the right, then Prue moves it to the left.
