Continuity mistake: The strap on Tahani's right shoulder drops during the scene where she is talking to her soulmate about how to dress. When Michael is there, it is up on her shoulder. At the end of the scene it is down.
Other mistake: When Michael walks into his office and sees Shawn, Michael is wearing a wedding ring. Looks like he forgot to take it off prior to shooting the scene. (01:00:00)
Continuity mistake: At the beginning of the episode while Michael is talking to the Judge, he does not have a Bad Place pin on his left lapel. However, at the end of the previous episode, as he and Janet come through the portal he is wearing one. On another note, not sure how he got the pin. As Shawn was talking to Michael in episode 11, he wasn't wearing one either and Michael had given his own pin to Eleanor. (00:00:01)
Factual error: As Eleanor walks in the corridor to Chidi's office at St. John's University, there's an exit sign mounted in the ceiling above her - a North American style red Exit sign. As she is in Australia, it should either a white on green Exit sign or an international "running man" style sign, as North American style signs were never legal in Australia. (00:20:55)
Answer: No, he is fictional. The joke is that, despite being handsome and charming, Larry Hemsworth is so overshadowed by his brothers that nobody else has heard of him and he feels like a failure.
