I just got to this evil evil part of the game I sadly neglected Atton as well but I'm not really here to complain about it. I just noticed this topic when I was poking around looking for info on a patch and figured I'd share a really bizarre thing that happened when the Twin Suns jumped me.
The first time I fought them I totally forgot that atton was sporting really really bad armor left over from telos so he died horribly. So I reloaded my game to take another crack at them when the fight started they didn't run at me like they did the first time. Instead they as far as I could tell from where I was standing decided to start fighting EACH OTHER! I auto targeted and killed the lighter skinned of the sisters (ironically with her own sisters help hehe) she died and the room went back to "normal mode" with the surviving sister just standing there like a normal nonagressive NPC and the door was still locked meaning Atton was still trapped I even tried to talk to the survivor all she does is giggle and says shes busy.
Thankfully I can reload from the auto save like the first death...but seriously that was really strange even for an apparent glitch lol
