It is truly difficult to describe the calm he feels in Perceval's presence. If Aegaeon were the type to be comforted by his own shadow, perhaps that would make an apt comparison.

The thought that he might harbor feelings for another, let alone another Blade (though he is absolutely certain that the nature of his relationship with an emperor of Mor Ardain could never deviate from a wholly fulfilling experience of filial devotion, his complete sense of devotion to his Driver can be nothing but tantamount to his very being), is no such calming revelation, yet...

The shadow, wondrously, remains.
