Okay so I did some digging about dybbuks and deals that a person has made with a dybbuk.
First in foremost Dybbuks are not recognized by the catholic church or christanty in general (which im assuming monty is catholic) they instead stem from Judiasim folklore. In Judiasim, Dybbuks are sepreate from demons. They are seen as "a person has died but is not yet ready to cross over as they have sinned without performing teshuvah [repentance] ."
Dybbuks also "fear the judgment that comes after death" therefore clinging to their victiums seeking a host. Something that monty is technically doing since we see Bee and Wills POV of hearing or seeing Monty as well as seeing his spectre leaving his body when Eula consumes it
Although there are some differences there are a lot of comparisons with the Dybbuks in Jewish folklore and Monty spectre, and we know that the reason why he is seen as the 'devil/demon'; due to how others viewed him when he was growing up.
what about the deal what are some of the comparsion to the folklore and the Nevermore webcomic? We see he has the powers of possesion, entering peoples mind, and fire/brimstone. We also see that his deal causes people to change their sense of self, whether its Will staying by Monty's side even though he does think about leaving. As well as Bee who distance herself from Lenore and her the team. Something that does get brought up when showing signs that a person has been possessed by a dybbuk in Jewish folklore. --Such as showing distress, Both the dybbuk and the victim remain conscious and co-exist in the same body, and the Dybbuks making them do things (saying slurs, committing sin, etc etc,.) they don't normally do.
Okay so -how does a person break a deal or get rid of a dybbuk? we know that Bee and Will might either need to complete the deal or end their lives to no longer do the deal -- and aint no way they are both willing to do that or how to even complete the deal (mostly talking abouy Will here) So what the best solution? The short answer is an exorcism. oh yeah his worst fears are coming true. But wait its not what you think, remember when I said Christanty does not regonized Dybbuks? That because in Catholicizim they cast out the evil, while in Juaduism does not exactly do that. "Lurianic Kabbalah believes that the exorcism of a dybbuk must include the tikkun, or repair, of their soul. Lurianic methodology requires communication directly with the dybbuk and negotiations regarding their soul. The "good" parts of the soul of the dybbuk are separated from the "bad" parts of the soul and returned to the Treasury of Souls. Once the "bad" no longer has a place to thrive, it will shrivel and die, leaving this world "--but how does this connect with spectres in nevermore' you may ask and to that I say remember in ep 3 when Miss Poppet told annabel that she can't fix her all the loneliness she feels "not right now" implying that she can change (or develop) her spectre through her journey whether its how she sees herslef or how much she is willing to change. Montresor is no different he'll have to confess his secrets, his mistakes, and his regrets. ( It'll also push his path more into his redemption arc too.)
who can do an excrosim? Who knows enough about spirits and ghost?
Eula. I mean Morella can help since she's a nun but mostly Eula. Girl knows a lot of things about ghost since she wanted to be a paranormal detective. Plus Bee is her bff so whether Bee likes it or not she has to fess up on why she's acting so weird with the gang.
If this is somehow not possible maybe because monty does not want to confess or something somethin happens. Bee or Will do have an option to kill Monty --which will be very difficult for Will since the deal might be his friendship/relationship with Monty. But not for Bee, although I don't know if they'll have to kill him in his spectre form causing him to wither completely end his spirit and ending the deal that is link to his spirit and Bee and Will's spirit.
Anyway thats all I have for know might do a little anaysis on Will's spectre and some theories on what his potentials and limitations.
