And besides, if Ruby already knew it would take away the dramatic effect of her realizing Yang isn't her real blood sister, and as you said there's been no evidence she even suspects it. So when she does find out, it could do wonders to lighten the mood of the darkening story.

Ruby: Say, Yang?

Yang: Yeah Ruby?

Ruby: I've been thinking... you say I look just Mom right?

Yang: Yes.

Ruby: But... you don't... um, is there... something I need to know?

Yang (deep sigh): This could take a while.

Ruby: W-w-w-wait a minute! H-how could, how could Dad do this to Mom?

Yang: This was before he got togther with Mom.

Ruby: But- but that's not right! He shouldn't... do that with anyone else but Mom. That- that's cheating!

Yang: Cheating?! You can't cheat on someone you're not even with Ruby!

Ruby: Yeah, well, uh, Dad should know better! He's not allowed to be with anyone but Mom! And there can be only one!

Yang: But Ruby, if he did that I wouldn't be here now.

Ruby: Sure you would!

Yang: Oh, and how?

Ruby: From Mom of course!

Yang (groans in chagrin, slapping her hand over her forehead)

Something like this anyway.
