There is someone else involved here who is perhaps even less forgiving than Reno, someone willing to go to great lengths for vengeance that seems justified because of the act the princess is speaking of right now.

"Without Endymion," she says, "there was nothing else." If the myth had existed in Reno's world after all, she might recognize the same grasping feeling that led that Selene to send that Endymion to sleep, simply so as not to lose him, even if he was nothing but a beautiful shell - an immortal fretting for the fate of her mortal lover.

The words, no matter her feelings, cut out the vast numbers of people who lived on that planet, and even her own companions and guardians and those who should have been in her heart.
