How to find the underlying scene of an instance?

[winged tinsel]

I'm keeping a reference to my main character's scene, and when characters register (main + NPCs) I want to distinguish which character is the main one. I want to compare that character node's original scene (its prefab/blueprint if you will) to the one I have as an @export var. How do I find this?
