Meh seriously after the PTSD, here is another theory to explain something that does not make any sense.
Once again like in many threads, when the story of BG3 lack of coherence people are crafting theory in their head to explain what is not possible to explain.
When people have to imagine things in their head for such details... There's really something going wrong.
It makes perfect sense that he's used to giving orders to more people. This isn't bending over backwards mental gymnastics.
If anything, I feel like people are bending over backwards trying to find reasons to hate.
Yeah perfect sense that he's at the door asking to open because they have been slauthered then suddenly forgot they have been slauthered.
He's shouting "form a line" like a captain would in an army. It's not a reason to hate, it's something I found ridiculous since day 1 and that I still find wierd in every playthrough.
No problem if you don't but don't try to get into Aradin's head. He hasn't write BG3's dialogs. But maybe Larian's writer when it was time to write this cinematic were thinking something like you......... (Probably not).
