I've been trying so long to get this scene to play out - the bit where he tries to (halfheartedly) convince you that reforging the Crown is both in your best interests is the common timeline.
Yes, it's bittersweet when you promise him that he's much more than godhood and in response he looks to you with insecurity and disbelief. He broke my heart even after the shaky acquiescence that I even suspected for a while that he'd go back on his word and go on with his hubris. He didn't, but the frequency he'd suggest seizing power made me uncomfortable until we all met at the docks in the end.
When you dissuade him from the start - not like all my reluctant enabling - he actually shows remorse for the mistakes he made in the past and vows definitely to make things right. He earnestly apologizes (!) to you, contrite and loving.
The only thing that rubs me the wrong way with this is how Mystra seemingly takes all the credit for our efforts.
