Re: Harry and the Feds/Librarians...
Worth remembering that Lara has been working hard to insinuate herself into the federal government. Back in Changes, she was able to whistle up a helicopter from an aircraft carrier to evacuate the wounded from Chichen Itza. (Which means the Feds have a report somewhere about Molly and Mouse...)
The next time Harry sits down for a chat with the feds, it won't be as a two-bit P.I. terror suspect whose office was just blown up. He'll be the fiancé of an influence peddler with hooks in senators and governors and cabinet officials.
Of course, that comes with all kinds of costs. Some honest feds like Tilly may be far more suspicious of him because of that. And the White Court comes with a new level of social infighting and manipulation on levels that aren't really Harry's strong suit.
(See the Dresdenfiles RPG, with its three modes of combat -- physical, mental, and social. The last is Harry's weak spot. He's at an insane Superb(+5) for Conviction, used for mental conflict, what he'd describe as will or willpower, but an awful Average(+1) for Presence, used for social conflict.)
His next big power-up is going to have to be learning to manage his reputation and relationships better. Heck, Peace Talks/Battle Ground *should* have taught him that. Now Mab's throwing him in the deep end of the White Court where he'll either learn or die.
