I was confused because it seemed like you were disagreeing with me even though we were both saying the exact same thing.
We both agree that an important lesson for Rey to learn is that it is her spirit and heart that determine her value, not her heritage.

I was simply suggesting that Leia should instead know there is something awry with her heritage, but isn’t able to place her finger on exactly what it is. She still decides to train her despite detecting this. That way you patch up the messy plot hole while achieving the same effect.
