I still haven't reworked that scene on Sunday morning.
However, I think it's important to note that Jack's guilt and redemption are a big part of the game. Even if I rework the breakfast with Cassie, that won't change. What the headmaster did, Jack's attitude and so on aren't going to change. Those are things that are or will be explained later during the game. So if you don't like that, Summer Scent may not be a game for you.
