Hi there! It might be a little late to ask this, and I don't know if you've been asked before, but Im really interested in the opening of your LBD fic "Everyone Needs a Confessor.". I found Dr Gardiners lecture to be really insightful, I was wondering if it was inspired by something you studied in real life, and if that's the case if you could recommend somewhere that I could read more about the concept?
There are two parts to this answer - the first if you're asking about literary theory and the second if you're asking about story telling in new forms of media.
I wrote that story at the same time as I was working on my critical thesis for grad school so I was hip deep in literary theory.
James Wood in How Fiction Works makes the argument that as the novel developed writers developed new ways of letting their main characters confess their internal thoughts. They talk to someone or write in journals, but eventually that "mind speak" became internalized so characters talk directly to themselves and to us. We become the confessors (a confessor is the one who hears the confession, not the one giving it) and suddenly the 4th wall is broken just like the soliloquy in theater.
The novel has its roots in the theater and prior to that in religious biographies of saints and martyrs. Stephen Greenblatt's Will in the World: How Shakespeare became Shakespeare has a great few chapters on this.
So I would start with those two books if literary theory & history is what you want.
If you're more casually interested in how stories can be told across new forms of media, I'd start in a few places. A03 is run by the Organization for Transformative Works, which publishes an academic journal online on all topics related to media, fandom, and audience. Academic writing can be a bit dry, but if you're into the paper topic then it'll be the cat's pajamas for you. Story Code is another non-profit that has some case studies on transmedia story telling.
And just for kicks here is a essay I wrote about Lizzie Bennet Diaries, story telling, and the audience as confessors.
