Scene: In Haven Yang is watching Ruby train with Qrow as Jaune approaches her
Jaune: Hey Yang? I have a stupid question.
Yang: Then I probably have a stupid answer.
Jaune: Why does Ruby take after Qrow so much? I mean her weapon even her fighting style are like his.
Yang: When we were kids Dad would train us in hand to hand combat. Obviously I loved it but Ruby took to it like a fish takes to skydiving.
Jaune: That bad huh?
Yang: She couldn't even throw a freaking punch! Anyways one day Qrow stopped by and was showing off with his scythe when Ruby started copying him with a tree branch. He saw that she really took to using a weapon like that and began training her. In time she began copying him, though dad put a stop to that when she tried to sneak one of his beers while he wasn't looking *she laughs* She thought it was root beer! That answer your question?
Jaune: Yeah.
