Absolutely not all of Lasciel's -- not a literal Fallen Angel -- maybe all of the Shadow's knowlege.
Yes, the Shadow did in my opinion, the Shadow was Lasciel in Harry's head. That's why resisting it once that happened was such a big deal.
But I'm pretty sure Bonea won't suddenly become (for example) Harry's Guide to the Starborn Phenomenon; I do expect she'll have some highly-pertninent Starborn-relevant info, though!
In my opinion it doesn't matter whether she becomes Harry's guide about Starborn Phenomenon, he needs the information, that's important, but not as important as what Harry does with that information. However the main thing Bonea has to do is grow up or at least mature a bit. As she is presently, she is a pretty useless character, which begs the question, why all the drama over a half dozen books or more to end up with what?
