I can totally get behind an elf or half-elf Kravitz, but in my heart he's human, because I like to imagine something like:
alive, pre-reaper young adult Kravitz who's been reading too many romance novels: "I just want a beautiful and handsome elf boy to sweep me off my feet... and of course romantically grieve me when I, a human, inevitably grow old and perish in his arms... perhaps even fling himself into my grave..."
Kravitz several centuries later, indeed dating an unfathomably long-lived hot elf boy who is nevertheless the less immortal one in their relationship: "hmm. interesting."
