There was some points from the BoS that seemed to have said danse had grown up with them. not child per say, but young probably 20 something. This was why I was certain there had to be a real danse since as you said (and I said) child synths didn't exist yet, so danse must have existed. It'd probably be easier if I knew what age Danse was supposed to be. My best guess is 35 or so (line of work makes him look a bit older). There is the thought that they call danse missing since he has gone native, but yeah since I didn't trust the institute I went to war with them rather fast, and losing danse only made me hate them more since I of course assumed he was replaced. Either way I'd like the mod. I want a BoS follower with actual dialogue so making a modded scared older danse model get danse AI and maybe a new perk since it's the human danse and boom.
