Monty also said something in his interview with AfterBuzz on Thursday that he's planning on eventually having an LGBT character, so if that's not too "mature" for kids, then there's no reason divorce shouldn't be a viable explanation for Yang's parents no longer being together/Summer & Ruby coming into the picture.

Also, as someone mentioned above, Torchwick already made a joke about divorce in "Best Day Ever", so it's clearly not something the writers aren't open to discussing.
