Keltham spends more time, sort of losing track of time actually, not least because he does not have a wristwatch or any other means of keeping time, and taking away a dath ilani's wristwatch when they're already in the middle of asking Additional Questions is sort of like yanking the breathing tube out of somebody who already wasn't breathing.
He acquires a slightly better and still incredibly confusing picture of Golarion theology, with certain selective omissions and alterations.
