Playing through the Shivering Isles again, and read up on the Wiki that you can offer to push Hirrus off the wall via a dialogue option. However, no matter how many times I reload the quest, I am never given an alternate dialogue other than the default "make it look like an accident" monologue. Is there something I'm missing, or do I need to wait a certain period of time after he stops at the ledge? To my knowledge, I have no mods that affect quests in the Shivering Isles...

Thanks in advance!
