I'm thinking the PC is so far removed from his draconic heritage that
the best he can transform is a pair of wings and his pupils have become
snake-like/draconic.
Powerwise, I figure Dragonsense, Flight and maybe elemental resistance
should do for now. Trust me, he doesn't need to have a breathe weapon
to kick butt.
Besides that, the sudden ability to grow wings coupled with his eyes
looking even more strange (he's death-touched which means he's equally
decended from undead) to the PCs should be enough to make them go
"WTF?!" and have him wonder about his heritage. That reminds
me... What sounds
like a good spot check to notice someone's pupils have changed?
