The season 2 finale wraps up various plotlines.
Portia has departed, but she left a note for Frank instead of ghosting him.
Rolph still hangs out with Pete, apparently as his “friend who knows your whole schedule” rather than his submissive. Pete has put Josh behind him, but is still uncertain about Tiff, and his career in comedy.
Tiff and Doug have reconciled. She says she loves him, and knew it was because she was vulnerable to him. She even offers to show him around the dungeon sometime.
