I'm at a point in my story where the main character(M17) was in a huge car crash. He'd been in an overturned vehicle for about 10 minutes and had sustained heavy damage. A few of his friends had come to his aid. At first, I had made a character(F18) break down after someone else(F17) who is overprotective of the MC put the blame of the accident on her.
The one who had pinned the blame is traditionally a level-headed, rational person who tends to think things through.
The one who had the blame wrongly pinned on her has a very relaxed, upbeat, and cheerful personality, and tends to display a lack of lady-like manners.
When I reread the sections
her eyes started to water as she was hit by an overwhelming sense of guilt
she turned and walked out of the room, Alexander called after her, but she didn't answer as she didn't want to feel any worse, much less cry in front of them.
it just didn't feel right with the type of person she is.
I had a whole scene centered around her being upset and yelling and everything, and now it feels like I should change it out, but then the whole scene would have to get changed as well and I'm not sure how to do that.
So my question is: How do I make a character with a certain personality react in a certain situation?
