[You mean the whole "humans with magic" wasn't just a thing of the AU like he assumed now? Uh.] Are there really people like that here?
Resonance, it-- depends on the person and how connected to us they are. Someone could have natural talent for it since birth, but then live so long outside of the influence of the seraphim that they can't see us just like that. Most of the world is like that nowadays, which is why this place is so... confusing to me.
[There's definitely not some huge seraph influence here that he can sense so like. wtf.]
