Driscoll's Links
Driscoll notices Nahe's generally wariness and respects that. He's not too sure how to interact with them anyway, given how much of them reminds them of the times prior to the events of the game.
Nahe feels conflicted about Driscoll, as they don't have the same memories that Ardor had. Overall, they keep things professional - just, often at a distance.
Ardor is someone that Driscoll cares for deeply, and knows they've hurt him in the past. So for Ardor to want to interact with him despite it all...he's taking care to approach these matters, and do what Ardor thinks is best for him.
Ardor has a lot of colorful words to say about Driscoll, but he's still Driscoll, which makes them inclined to look after him. In post game, Ardor pushes Driscoll to try and be a little more independent - and more importantly, come to terms with what he's done to this world.
