A clown gets a prequel. That sentence is the entire essay, and I have written about this before and I am not going to pretend I have grown out of it. Fiction is a room we practise feeling in, at safe remove, and it is a genuinely good room. The rent in that room has now been signed for years.
Shipping, kinning, comfort watches, and the safest place on earth to find out what you actually feel.
Fictional bonds are the well-studied ones because they are the only ones with a fire exit. Dreamarched is a whole descent through that, into an architecture you keep going back to. The only line worth drawing is where the room starts making house rules, and you can always feel that coming before you can explain it.
