Audiobook inconsistencies.

So I've been listening to the audiobooks for what is probably the tenth time and I've noticed some inconsistencies in character knowledge throughout the audiobooks. The one that comes to mind first is that in I believe the first book Alice tells someone about the Internships (I think it's Vince) but in book three she seems to not know about it and Angela explains it to her. It's nothing big or super important, I was just wondering if anyone else noticed.
