Leia and Luke?

[Naiwen]

Before she's known that she's his sister, she has been having feelings for him. I don't think it could be called incest because she hasn't known about it personally.

 

[Flint]

It doesn't change that that it's an incest because of ignorance don't you think so? Ignorance of something doesn't change it from what it is in my opinion.

It wasn't an incest. Though the feelings was there but it didn't happen between them. And when she knew about it, she call herself to order and killed every feelings she had for him.
