She is very oblivious and innocent! Carissa not having any idea what's she's about to walk into does make Keltham feel rather supervillainish, to the point where he has to fight back his conscience questioning whether Civilization would really, honestly approve of all this.
Carissa has been very very loud about wanting him to try more things in the cuddleroom, wanting him to take more risks, he checked under suddenly truthspell if she really believed he could trust what she was saying, and she did. They have known each other for three whole days now, and it's time to move forward on ambitious third-date activities, like negotiating fallback ownership options on her so that he can safely rent her to the Queen of Cheliax as a romantic surprise. If he can't do even that much, their relationship is hopeless!
Dath ilan spends a great deal of money and energy trying to prevent its very smart people, or even average-smart people, from getting bored.
So far, in Keltham's experience, Golarion is doing legitimately better at this. Credit where it's due.
