For the characters, Season 3 was about expansion—both of the ghostly roster and the emotional depth of the characters. Episode 7 showcases the writers' ability to weave together multiple storylines. The chemistry between the cast, particularly the improvisational roots of the Horrible Histories alumni, shines through even more in HD formats where facial expressions and background details are visible.
The ghosts learn that a poltergeist can change hosts through a painful process Saul jokingly calls "jerking off". To stay with Alberta, Saul tries to transfer his tether from the departing dentist to Jay, which would mean Jay would have a ghost following him everywhere—even into the shower. ghosts s03e07 720p
