Harry noticed it in Sith because he was directly breaking his word and his bonds, and the Sidhe just don't do that.
Yea his keen investigative abilities.
Justine and Lara still have some form of proof they are infected, even if it isn't the most trust worthy source.
I assume you mean aren't infected, I agree, but its not 100% assured, and with Nemesis its almost safer to presume infection then not especially where bad girl(s) are.
When did the White King stop Aurora? Also, he works with the Outsiders directly and has them blocking him from magic
that was me free thinking and combining sentences. I meant I wasn't sold, because Harry had already been a thorn in his side and would have been removed at the mansion fucking the rules of guests.
In fact, I think I can state that the White King isn't infected, because he still put propriety on the standards of his court and behaved in a normal manner. He utilized the outsiders as tools and weapons, but was still a weakling in the end of it because Harry's Mom's Curse. If he was infected the curse too Might have been shrugged off.
