I don't think so, but maybe he can add a little more content for a character without 'betraying' his initial vision. It can result in a longer scene, or a secondary event / DLC
Everything is not set in stone either.
On several occasions, he indicated that he still had to work on certain important characters.
He withdrew Dylan's confession, but if he did, it shouldn't have changed much in the end, otherwise you know very well that he would have got a little angry by saying that it's important to keep it and only his opinion matters. whatever... the artist's choices are up to the artist. It's obvious but it must be remembered
In my humble point of view, he can do a few variations if he thinks it can be nice without moving the lines too much. The only thing I wish is that you had enough content with Alyssa, and
farrah had enough content with Ellie
