When a redeemed Dark Urge completely rejects their Father, the camp conversation with Minthara after Orin's death will have a line for redeemed Dark Urge still considering themselves as 'part of the family' with Minthara acting as if Dark Urge accepted Bhaal's gift and mastered the Urge in order to dominate the world.
This line should not be available at all to a redeemed Dark Urge, as none of this is true.
*I think Orin bumped you a bit too hard on the head there Minthy*
