But a multithreaded story can offer many voices at once without giving any one of them the last word. This is a reassuring format for encountering a traumatic event because it allows plenty of room for conflicting emotions.
Here the author is contrasting linear story telling and multithread story telling. This can show how a single version of an event may feel limiting, specifically in context of trauma. The multithreaded version can validate and express multiple perspectives and emotions which I think relates nicely to Hana Feels as we experienced multiple perspectives which I thought helped the story develop.
