When Alison interrogates the ghosts about what exactly it is they want, Pat says that he just wanted to say hello. When Alison angrily snaps "Hello!" at him, he cheerfully responds in kind and tries to start up a conversation, as if they were just introduced at a party.
Fanny's only demands are that the portrait of her hated dead husband be removed from in front of her room, and that Mike fix the hole in her wall he made while trying to fix it. He patches the hole... with the portrait, making the late Lord Button's face stare directly into the bedroom.
Happy Death Day
