Although I am liking that the entire family turns on him on a dimeI'm sorry.. But i can't stand that old man anymore. Every chapter with him makes me annoyed
Also that girl seems a little too calm. I wonder if she's like Luca
Please don't be annoying We have enough with that grandpa already
Since it's already been heavily hinted at that Luca has regressed to the "novels" beginning. I believe that Charlotte has regressed as well, but Luca doesn't know that and feels that if he gets involved with her than he would be putting her in danger due to his romantic feelings towards her.
Another theory I have is that the events of the "novel" have happened multiple times now, but with slight alterations, and that Judith has lived through them all. Which is why she saw those memories of scenes that weren't in the original novel.
In short, she's the original Judith, but her mind can't really cope with the fact that she has regressed for so many times that she has come up with the excuse of being inside of novel so that her mind can slowly come to terms with everything.
