There's no harm in sharing this aspect of himself with the angels, Dorian reasons, because he's reasonably sure some of them already know-- Sin and Lucifer definitely do, at least. "I heal immediately from any physical slights my body may suffer. That, and I can die and resurrect without issue." He'll leave out the part about his lack of a soul and the extra benefits that confers, but given how Lucifer was able to tell he didn't have one simply by being near him, it may or may not be pointless to withhold this particular truth from any of the angels. "I still feel pain, but as you can probably imagine, being able to heal and resurrect takes away a lot the dangers of living an immortal life that ordinary humans, or immortals that can die from physical wounds wouldn't be able to face as easily."

That surprises Dorian a little. From the careful and elegant way the angel is dressed, he would have figured him for someone who enjoyed such material objects-- the gems, at least. "No? So, if I'm understanding you, it's the value of those objects and how they're used that you like?"
