Kravitz clears his throat, trying to keep himself some kind of calm and composed instead of a raving nerd. It's hardly that he's intimidated by Crowley and more that he's concerned about the social missteps here. He certainly wouldn't have felt good if unknown people knew too much about him when he first arrived, so it's understandable. He's just been told to chill out like, a lot, so an attempt is being made.

"To make a long story short, in my world, I am a servant of the Goddess of Death. Most people here seem to recognize the Grim Reaper, so I'm hoping it carries. I was very much not simply mortal before I arrived here, but upon entry, I was stripped of many of the benefits of not having a solid body. Everyone on these islands, it seems, will need to eat and sleep or we will succumb to hunger and exhaustion." He raises an eyebrow towards Crowley, looking to see his reaction. "You may still have some of your abilities. But not those ones, for certain."
