Can I weasel out and say that it could be both? We know so little! All I get from her scenes with him is that she was very much in love with him, and that she was happy when he was with her. I also see a sad but graceful resignation to his absence when he left her, even though she continued to love him, and even though one might think she'd want to cling to him as long as possible, knowing that he would die much, much sooner than her. I can't tell she able to let him go because she was thinking on Mazoku time ("we have forever, so separation now is bearable"), or because she valued his happiness above her own.

It's safer to assume Conrad's early acceptance of mortality, both Dan Hiri's and his own (not that that stopped him from reacting very badly when Julia died--was that because romantic love is different, because she died unnaturally, or because she was pure-blooded Mazoku? She, uh, was regular Mazoku, right? It's been awhile). I'm sure Conrad could tell his father was near death, and if Cheri hadn't anticipated it before, she surely saw it when he came back the last time, but at the end of the episode, Cheri is the one weeping for Dan Hiri's mortality, while Conrad peacefully explains his own to Wolfram. And I imagine that would only have been reinforced in battle. How bitter it must have been, for the halfbloods, being asked to sacrifice their lives for the immortals, when they had many fewer years to begin with!

>_> Whoa, I'm being all poetic-like. Someone should slap me upside the head with a trout and remind me that KKM is crack.
