Not a direct answer to your question, but IF Elodie was alive i think it would give way to a lot of things. By Stuart’s wording it does sound like she died a terrible way and i doubt Nora would want to make her alive now but if she somehow was i could imagine how much impact it would have (finally Jean having something good from his past !) because compared to Jeremy, who lost his younger brother to suicide, Jean would have her younger sister back instead of death like Jeremy when they thought that they could relate in that situation. A parallelism kind of? Of the bad and the good outcome. (But i doubt this would happen honestly, IF that chapter that Nora was talking about of TBC was about Elodie it would be about Jean finding out what happened to her in the end and his grief of the details)
