There are several continuity errors in the final scenes.
Cassandra and Jake met when she came down the stairs of Grey House, but they are in the heritage centre when they both talk about falling in love when they first saw each other 'on these stairs'
George talks about staying 'here' suggesting he is in Grey House, when he is still in the Heritage Centre.
Watch for a couple more. . .
When Betty comes into the Bell Book and Candle and Cassie is waving incense around, she says it is because people are extra stresses at that time of year and its soothing, but the incense isn't actually lit.
