I don't necessarily mean that Ansom has had some kind of magical compulsion to change his point of view (though it is possible that this has happened - just as it's possible that some weaker version, a kind of magical nudge, could have happened). It could just mean that being brought back by a literal tool of the Titans means he has to believe that decrypting him was the right thing to do, and thus has to (force himself to?) align his thoughts those who were responsible for his return. Really, it's hard to say at this point - and I do hope that ambiguity continues for a while. Dramatic tension...
Thank you! I'm glad I'm not the only one who feels this way...
