When Jackson grabs the candle stick holder, the candle is on the table, but when he attacks Andy, there is no candle on the table.
In this episode the ghost was supposed to have been executed at Alcatraz and trapped there after his death. No prisoners were ever executed at Alcatraz.
In the scene where Jackson is burned by the grave potion in the transportation garage, the City seal on the truck is not that of San Francisco (where "Charmed" is set), but is that of Los Angeles (where the show was filmed)
Andy asks Prue how long she gave him to think about her being a witch and she said a minute or two. This is not correct. In 'The Truth Is Out There... And It Hurts,' Prue gave Andy a couple of hours to think about his answer, but she needed his reply before the truth spell ran out so she needed an answer a couple of minutes before 8 pm.
