Continuity mistake: In the scene where Agent Jackman shows them the file he has on them in their dining room, Paige's left dress strap has fallen off her shoulder in some shots, but in others it's perfectly in place.
Plot hole: In episode 1-2 ("I've Got You Under My Skin"), Alec buys Phoebe a martini at Quake. but then in episode 5-11 ("The Importance of Being Phoebe"), Cole tells Kaya that Phoebe doesn't drink. Then, in episode 5-17 ("Lucky Charmed"), Jason buys Phoebe a "Martini, dirty" at the end.
Plot hole: Paige says she cannot wait to tell the local witch doctors that Borneo demons are not impervious to magical powers. But in the episode 'House Call', they act as if they have never heard of witch doctors, let alone dealt with them. (00:01:45)
Plot hole: The Sea Hag says at the start of the episode to Mylie that as an immortal being, only she can place the augur shell over her heart to give up her life. But at the end of the episode Necron magically places the shell onto Phoebe and it nearly sucks the life out of her. (00:03:20 - 01:14:55)
Plot hole: In this episode, when Piper and Leo are preparing the nursery, Leo tells Piper he has been watching her her whole life, and she says "That's a little bit creepy". she acts as if she doesn't already know this but in episode 2-22 'Be Careful What You Witch For' Piper says, "You have been watching me my entire life". (00:04:45)

Continuity mistake: In the teaser Piper is reading a fairytale book to her unborn child. When Paige walks in we get a glimpse of the book, and both pages are filled with words. When Paige walks out and we see the book again, the right page of the book has a picture on it. (00:00:15 - 00:01:35)
Continuity mistake: When Adam spills coffee all over Phoebe's top in the office, the stain disappears and reappears between shots. (00:08:05)

Siren Song - S5-E4

Siren Song - S5-E4
Visible crew/equipment: While Leo is at the manor with Phoebe, who volunteered to make the potion, when Piper and Paige orb into what's left of Melissa's home, through the hole in the wall we can see the boom mic (with a white striped tip) hovering over the sisters, just as Piper tells Paige she doesn't want to make Melissa more upset. (00:24:45)

Character mistake: When discussing how best to help Melissa, Piper tells Paige that her birth father was half whitelighter, when he was fully a whitelighter. (00:25:15)
