I'm playing as a Priest of Wael and Grimda doesn't seem to recognize this at all. Getting the scroll and then listening to Wael and hiding it results in Grimda ignoring me. So...I'm playing as a priest...of Wael...with Clever and Deceptive as preferred Dispositions, yet Grimda says something like [Deceptive 2] 'I should've known better than to trust you. You're every bit as wily as those thieves.'
Uhhh...wha? Talk about odd dialog.
