You know if it was simply stated that Jean's sacrifice to bring Clare back from awakening is what prevents her from awakening again I would have no problem.
But my problem lies with the stupid ass explanation of how she has an personal mental barrier she herself isn't even aware of type of crap that just makes the writing look flat out bad. And having it explained by the side spectator only makes it worse, like why tf would she know what's going on in Clare's mind. Ugh this was a frustrating development in what could have been a solid chapter.
