Emma's phone rang when she pretended to have a phone call, but it was broken.
When jessie has her hand glued onto ms chesterfields arm first it is on the inside of the arm but in the next scene it is on the outside of the arm.
When Jessie gets glued to Mrs. Chesterfield's arm, her left hand is on the arm and her right hand in stuck on her left wrist. Hoever, when they exit the bathroom, the hands are switched.
It's obvious that Jessie's hand is not stuck on Chesterfield's arm because she can been seen moving it, and her palm can also be seen. If her hand was really glued to Cheterfieild's arm, her palm wouldn't be seen.
