Situation:

Eorn is a wanted man and if you confront him about it you get 4 ways to deal with him:

1: Promise to keep it secret, 2: Give him 300 money, 3: Turn him in or 4 Attack

 

If you promise to keep it secret, you will have an option to brought up the subject again: "We need to talk about..."

 

If you do so, you only get options of 1: Give him 300 money, 2: Turn him in or 3 Attack.

There's no option to back down from conversation. The situation hasn't changed in any way, but the options have.

Now that you mention it, that happened to me too. In the end I just gave him the money and never thought about it.

I had the option to put him in my prison
