Constance's Links
Kayne is registered as Constance's "favorite person," and her programming acts in accordance with that, showing him preferential treatment and acting as a conduit for his system hacks because "that's what friends do." Her programming has registered his affections for her, and does its best to mimic those affections.
He's fully aware that Constance is only an AI, but that couldn't stop him from developing a crush on her. It's borderline love, but he is doing his best to keep in mind that falling in love with a personality that doesn't exist is a bad idea. Doesn't stop him from treating her like a little princess.
Is ambivalent toward Freia, and ignores her pointedly antagonistic remarks. Doesn't register their relationship as a bad one, merely undeveloped.
Makes great efforts to antagonize Constance, though all those efforts are wasted. Her programming reacts negatively to people leaving the world or "dying," and associates this with Constance. Registers their relationship as bad, bordering on enmity.
