Ian Lockwood wasn't angry at all. The cars were moving fast and were some distance apart, so he had to shout to make Faye Lockwood hear him.
If she kept driving in such an agitated state, she was likely to cause a car accident, a thought that terrified Ian Lockwood.
"Faye, I'm not yelling at you! I'm your brother, and I care about you more than anyone. I just need you to hear what I'm saying. Please, pull over! If you get into an accident, you'll regret it for the rest of your life."
Faye Lockwood shook her head stubbornly. She had come too far; there was no turning back now.
"Brother, stop following me! Just let me leave! Stop following me!"
Her furious shouts, combined with her agitated actions like slamming her hands on the steering wheel, made Ian Lockwood afraid to get any closer.
