@Tsundoku Looks good, except I'd wonder about "incident" as a motif. I definitely would not put it first among the list of possible motifs, as the tag wiki for
theme currently does. The tag wiki for
motif, which specifies "kind of incident," is better. Also, objects can be motifs—if powder puffs show up in several houses in a novel, I'd start wondering what's going on with powder puffs in that novel.
