As a guest in their house, on a mission to help resolve their strained relations, the Main Character has to show some restraint and keep his fists of fury holstered. Otherwise, he’d risk living on the streets, or worse.
Now, I get that some players want more of a reaction in certain moments, especially regarding Fred and early Emma interactions. Some dialogue changes will be made before the very end, but they won’t be major and there will be no violence, ever. (The wedgie performed by Angela is as violent as it’s ever going to get)
The way of dealing with Angela by sending her to the principal’s office and not tearing her a new one, is in my mind a happy medium. Effort can be put elsewhere while also not souring the mood too much.
