How do I write -The main character learning they aren't human- without being cringe?
So in the story I am working on, the main character (Character A) has no idea they are half -insert fantasy race - and I have been building up to the reveal, but I am struggling to write her reaction to the news/Someone (Character B) explaining it to her.
Obvious shock, right? But how can I convey that through dialogue or actions that won't give me and the reader the ick?
also I REALLY don't want this to be a "You're a wizard, Harry." moment. just a moment of "So the thing I initially thought was wrong with me way wayyyy off."/ "My whole life is a lie." kinda vibe.

some context:
-mother is dead/ abandoned by father, so they don't know what they are
-raised by someone who is not -insert fantasy race-
-they move out on their own and end up living with 'Character B' who is suspicious they could be -insert fantasy race-
-'Character B' gets sick from a known weakness to this race, Character A witnesses the transformation/the truth is revealed, and then they're basically gonna be like "Why are you acting shocked about this? We are literally the same thing. You've just been lying this whole time, and I was trying to get you to admit it." (they dont realize 'Character A' has had no idea this whole time.)
