Yeah no, act 3 is pretty lackluster by way of Durge moments. You'd think that now you're back home- in your hunting ground- with the realisation of what you are, that there would be a few more interactions there.
No flashbacks in the temple? No random people on the street who might recognise you? At the very least, we should have some kind of scene in your old bedroom, you know?
And also, you know, no real unhinged urges to contend with? I know you're at a point where you're either getting a hold of yourself, or embracing your nature, but no more options to do some crazy shit? If anything, especially if you're resisting, there should be more pushback from Bhaal, right?
