Plot hole: Alex and Jack go to Liverpool St. Station to find the guys from Jeff Slater's. This is on the day of the funeral, otherwise it would make no sense going there. But when Mrs Jones sees Alex, she says "shouldn't you be at school?" This makes no sense because Alex would not go to school on the day of the funeral. It's not a character mistake because Mrs. Jones would never make that mistake.
