If I were in Angela's case, had her life and didn't know anyone, my mom didn't recognize me and the only person who knew who I was was a physcologist, I'd be taking him straight to the police station and have him vouch for me. Would have saved me a week of nightmares.
No...... There was plenty of time for Angela to take Alan with her to the police. They went to the motel. Instead of going to the motel, they could have gone straight to the police. That Jack guy or whatever his name was had no clue where Angela was. They had tons of time before Alan was in the hospital and died. I'm not saying that it was Angela's fault for getting herself in the situation she was in, but she could have very easily gotten herself out of it rather quickly. If I were Angela, I'd be doing just that. No matter how tired I'd be from traveling. I'd want my life back more than wanting sleep.
