The Things are back to normal, kinda Ending is an ending in Prisoners of the Elder One. It occurs after leaving through the golden doors while Tiffany is rescued, but still a catgirl.
Erik wakes up in his own bed, assuming the prior events to be a dream. However, Tiffany still has cat ears and a tail. She refuses to go to a hospital for fear of experimentation, and decides to keep it a secret, playing it off as a cosplay. As time goes on, however, she realises that not all the mental changes have left her, leaving her hornier than before. Eventually she starts a career as an AV actress and makes a decent living off of it.
