"If even you admit there's a chance he might not come back, why're you refusing to treat any of our gods since like they're really our gods? That's why you don't use -sama except when you're talking about Axel-sama, right? 'Cause you don't really think of anyone but him as your god." Ken looks troubled as he watches Chikusa. "So...we don't have the same loyalties anymore..."

Not that Ken thinks Chikusa isn't loyal to Hakkai or Nanako at all. But he can tell Chikusa's holding things in reserve, that there's depths to Chikusa and his feelings that he's closed off to anyone but Axel. And there aren't many people who share Ken and Chikusa's deep devotion to the people they serve, so Chikusa's detached attitude with gods Ken has embraced wholeheartedly...there's a sort of strange loneliness to it.
