Rey, I can't judge you for who your family is. And I wouldn't want to even if I could. Who you're from doesn't change who you are.

[Sorry, if she wanted some sort of big reaction to the news, not going to happen. If his dad is actually Vader, why can't her grandfather be the emperor? If anything there's something poetic about it. Their families being so closely tied to each other.]
