Talking to yourself does tend to lead to that kind of thing, but you can always make one side somewhat uncooperative or clueless. Just because you know the right questions to ask doesn't mean your characters do, and likewise, just because you want to give information doesn't mean your characters do. Figure out how the characters would handle it knowing what they know.
Say, on the subject of interrogations, should I play the Public Works Guild pony Night Jewel and Zaros/Dawnstride will have to deal with, or will someone else volunteer? And I'd appreciate an answer this time, whether it's a yes or a no.
