Seventh If he is, then Monty lied about Ruby and Yang being half-sisters. However, no one on the RWBY crew, including Monty, ever lied to us intentionally, especially since Rooster Teeth values its fan community and prefers not to lie to us.

There was absolutely no reason for him to tell us they're half-sisters, but he did anyway.

When asked questions they don't want to answer because of spoilers or plot twists, they don't lie, they just don't answer, make a joke, give us a tease, or tell us half the truth.

Ruby and Yang are half-sisters. If Qrow is Ruby's real father and Raven is still really Yang's mother, that would mean Qrow had sex with his own sister.

Which I highly doubt.
