Arguable the weirdest and most confusing part of "The Case of the Very Long Stairway", Limbo is portrayed as a hotel lobby where everyone there is frozen in place, ringing the call bell at the service desk causing them immense pain. In The Divine Comedy, the primary inspiration for the Circles of Hell trope used here, Limbo is meant to be the place where those who were morally neutral, who were neither sinful nor virtuous in life, reside. When you take that into account, this whole section is ripe with Alighierian irony: a lobby is a liminal place, neither outside of the building nor accessible to the hotel's services. The damned there are frozen, incapable of acting for good or for bad. When the bell is rung, it is an action that demands the liminal state of being a patron or not a patron to be broken. Being neutral is portrayed as a source of unending torture (being frozen in place and fully conscious during it), with the brief seconds of freedom from that being nothing but stimulating pain.
The flowers that The Cat King gave to Edwin as a parting gift are lilies, this which are very dangerous for cats but it symbolises rebirth, condolences, commitment and purity of adoration and love. In other words, The Cat King gave the person he is interested in a flower that's deadly to him to pay his respects and express his commitment.
While Jenny didn't went through a major near-death experience like Niko, even after being both nearly killed by a psychotic stalker, and being possessed by a demon, she still now manages to see both the Dandelion Sprites and the Boys. While this would at first appear to be strange, it also does show to be consistent with how supernatural things happen in a lot of Neil Gaiman's and Vertigo Comics media, including The Sandman, Hellblazer and The Books of Magic, in which, once you make a step forward into believing in magic/the supernatural, there's no going back. Jenny had an extraneous moment in believing supernatural things, until she was slowly convinced about the supernatural happenings in- and outside her butcher shop. Once she convinced herself that everything was real, she was able to perfectly see everything with clearer eyes; she is already into the magical world.
It was a miracle that the bracelet that The Cat King placed on Edwin to trap him in Port Townsend disappeared when the latter was dragged back to Hell, otherwise the creatures of the Hell would not be Edwin's only concern.
Charles defines himself as a protector. The entire time Edwin was being tortured by Esther, he was chained up having to listen to him scream, unable to do anything about.
Speaking of protecting, imagine how Charles felt when Edwin was kidnapped by the Cat King. At first it seemed like Edwin was talking for a few minutes with the Cat King, but then it is revealed that in reality the conversation lasted for hours, more specifically it went from night to day when Edwin returned with Charles and Crystal. The only thing Charles knew during that time was that a powerful supernatural being kidnapped his best friend to punish him and he could do nothing but wait. Although the situation did not escalate, it is not surprising that when Edwin returned Charles was eager to know what happened in that conversation.
Edwin and The Cat King's entire conversation takes on a much creepier tone if you think carefully. The Cat King becomes obsessed with Edwin as soon as he sees him and at the moment when he was going to punish him they were in an unknown place where time works differently. The King proceeds to punish Edwin by trapping him in the city and offering to free him if he has sex with him. Fortunately, when Edwin resists, the Cat King gives him a different punishment, but what if the King had notaccepted Edwin's consent? Remember that Edwin is not a fighter and was without anyone to protect him against a creature that if he had somehow managed to kill in a few seconds the Cat King would be resurrected completely unharmed, plus it is not difficult to think that the room they were was surrounded by cats (who can hurt the ghosts) for the king's safety. That is to say, that in a fight it is clear that Edwin would be defeated and what the Cat King would have done to him afterwards.
The Detectives were planning to leave Port Townsend after rescuing Becky Aspen. Had the Cat King not trapped Edwin there, they wouldn't have solved Niko's possession, ended the Devlin Loop, put Angie back to sleep, or stopped Esther completely. This is one town, how many other places out there have problems like this that don't get dealt with because the Detectives, or people in similar professions, never hear about it?
