The one that stands out the most is that I told Hanlon that I was going to turn him so that he'd kill himself and I could get his Ranger Sequoia. I didn't know that it was a Semi-Unique and that Rangers would carry them.
The messed up part is that I agree with him. I'd totally let him keep doing his thing if I was going through again.
I also would have put off the showdown at Boulder City until I could pass the speach check instead of going in guns blazing.
