Keltham does spend a few more cognitive cycles than usual on trying to figure out how purposeful is that he can now feel her hair slightly moving, but nothing else; if it was dath ilan he wouldn't have to question the deliberateness at all, but Golarion is weird. Is it meant as a tease?
Maybe it's meant as a way of saying that he wants more, he needs to ask for... order for it.
Keltham rips out more of Carissa's other armpit's hair while he thinks, aiming for symmetry on round one, with that mix of gentleness and fierceness that he suspects is part of the Larger Thing. Is Carissa reacting in any interesting ways to that?
